Problem Description:
Intermittently, cfdocument will simply stop working completely. We're using the below code to generate a PDF, and it simply times out.

<cfdocument format="PDF">

You can set the timeout to be any length you want, and cfdocument will still fail to generate even a simple PDF. I've attached a stack trace from SeeFusion when the request was stuck as "cfdocument_while_running.txt". I've attached a stack trace provided by ColdFusion after the timeout as "cfdocument_after_timeout.txt". If any more information is needed, we're happy to provide it as this happens on a somewhat regular basis across several servers.

Steps to Reproduce:
Try to use cfdocument with any content.

Actual Result:
Error Occurred While Processing Request
The content of this document process takes more than 300000 milliseconds to process.

Expected Result:
PDF with the word "test" in it.

Hi, How often does this issue occur? Also, how much load is there in the system that the issue starts coming? Also, are you running some other requests too along with the one shared? Thanks, Kailash

Hello, The issue occurs intermittently. There is very little load. The server is a shared hosting server, so it's very likely that other requests are running at the same time when the issue begins. However, once cfdocument breaks, it will continue to timeout regardless of server load or lack of other requests. To be clear, once cfdocument quits working, there could be no other ColdFusion requests running and it will still timeout. Thanks, Cody W

Any chance we could get an update on this? This issue is intermittent and keeps causing us to have to restart ColdFusion. Each time, the stack trace is almost identical and gets stuck in the following pattern. at coldfusion.util.Waiter.getResponse( at coldfusion.document.DocumentProcessor.processContent( at coldfusion.document.DocumentProcessor.processContent( at coldfusion.tagext.lang.DocumentTag.processContent( at coldfusion.tagext.lang.DocumentTag.access$200(

Hi Cody, As we don't have a specific test case, we will see how best we could check this in the code. It always helps if you could share isolated reproducible code so that we can fix the same quickly. Thanks, Kailash

We have experienced this same issue. It seems the issue is triggered when more than one person hits the same cfdocument process at the same time. I would consider this a major issue as it impacts reporting under load.

We are implementing a pay-for-pdf system with CF, and have just hit this issue in a VPS environment. CFDOCUMENT causes the server to hang, then we get the Internal Server Error message after timing out. After this, any other CFDOCUMENT process encounters the same problem, even using this simple CFDOCUMENT code: <cfdocument format="pdf" mimetype="text/html"> This is a test pdf. </cfdocument>

Hi,   It has been 5 months since the last update. Just checking if this is working for you? If not, can we get on a call to see when the issue is happening? You can email me at [|]    Thanks, Kailash

This same behavior has recently represented itself in one of our production environments. <cfdocument> tags will suddenly begin timing out with no explanation. ColdFusion is stuck waiting on "processContent" as reported in earlier incidents. at coldfusion.util.Waiter.getResponse( - locked <0x000000072b969cb0> (a coldfusion.util.Waiter) at coldfusion.document.DocumentProcessor.processContent( at coldfusion.document.DocumentProcessor.processContent( at coldfusion.tagext.lang.DocumentTag.processContent( at coldfusion.tagext.lang.DocumentTag.access$200( This issue is intermittent and isn't reproducible. Restarting ColdFusion fixes this issue when it presents itself.

This issue has once again presented itself in a separate production environment. Here is the AJP request starting at CfmServlet that shows this behavior occurring. This request will eventually timeout on processContent as mentioned in previous responses. java.lang.Thread.State: TIMED_WAITING (on object monitor) at java.lang.Object.wait(Native Method) at coldfusion.util.Waiter.getResponse( - locked <0x00000007b3bd1c90> (a coldfusion.util.Waiter) at coldfusion.document.DocumentProcessor.processContent( at coldfusion.document.DocumentProcessor.processContent( at coldfusion.tagext.lang.DocumentTag.processContent( at coldfusion.tagext.lang.DocumentTag.access$200( at coldfusion.tagext.lang.DocumentTag$ at Method) at coldfusion.tagext.lang.DocumentTag._processContent( at coldfusion.tagext.lang.DocumentTag.doAfterBody( at cftestPDF2ecfm71332642.runPage(D:\home\\wwwroot\testPDF.cfm:15) at coldfusion.runtime.CfJspPage.invoke( at coldfusion.tagext.lang.IncludeTag.handlePageInvoke( at coldfusion.tagext.lang.IncludeTag.doStartTag( at coldfusion.filter.CfincludeFilter.invoke( at coldfusion.filter.IpFilter.invoke( at coldfusion.filter.ApplicationFilter.invoke( at coldfusion.filter.RequestMonitorFilter.invoke( at coldfusion.filter.MonitoringFilter.invoke( at coldfusion.filter.PathFilter.invoke( at coldfusion.filter.ExceptionFilter.invoke( at coldfusion.filter.ClientScopePersistenceFilter.invoke( at coldfusion.filter.BrowserFilter.invoke( at coldfusion.filter.NoCacheFilter.invoke( at coldfusion.filter.GlobalsFilter.invoke( at coldfusion.filter.DatasourceFilter.invoke( at coldfusion.filter.CachingFilter.invoke( at coldfusion.CfmServlet.service( at coldfusion.bootstrap.BootstrapServlet.service( --- This issue is sudden and begins occurring with no explanation. It could be weeks before the issue presents itself. When the issue does arise a restart of ColdFusion is required.

Hi Kailash, Perhaps 2 simultaneous requests hitting <cfdocument> triggers a deadlock w/ infinite timeout? Could you check that scenario? Thanks!, -Aaron

Reopening the bug as the user is still seeing the issue Can you please share the complete thread dump when you hit the issue? Do share 7-8 thread dumps taken with a time interval of 10 seconds gap between each Also, is there any case where you might have used a html img tag with empty source? It will look something like: {code:java} <img src="" />{code}

I'm seeing a very similar issue, but when PDFs start hanging on the server, there are two threads that get deadlocked which is what caused all other threads to timeout. Here is the top of the stack from the HTTP request that first hung and is deadlocked: "ajp-bio-8014-exec-1" Id=135 BLOCKED on com.icesoft.util.trackers.RenderDoneTracker@36c4a013 owned by "AWT-EventQueue-0" Id=1518 java.lang.Thread.State: BLOCKED at com.icesoft.util.trackers.RenderDoneTracker.propertyChange( - waiting to lock com.icesoft.util.trackers.RenderDoneTracker@36c4a013 owned by "AWT-EventQueue-0" at ice.storm.StormBase.firePropertyChangeEvent( at ice.storm.StormBase.sendViewportMessage( at ice.storm.StormBase.renderViewportContent( at ice.storm.StormBase.renderContent( at com.icesoft.util.PageDecorator.HeaderFooterDecoration.paint( - locked java.lang.Object@51cc3e14 at ice.pilots.html4.ThePrinter.printPage( at coldfusion.document.DocumentSection.print( at coldfusion.tagext.lang.DocumentTag.printSection( at coldfusion.tagext.lang.DocumentTag.doAfterBody( at cfehPDF2ecfc1151364043$funcPDF132.runFunction(D:\HTTP\site\handlers\ehPDF.cfc:160) And here is the other thread (not an HTTP request) that it is deadlocked with) com.icesoft.util.PageDecorator.HeaderFooterDecoration.renderingDone( - waiting on <0x51cc3e14> (a java.lang.Object held by thread 135, ajp-bio-8014-exec-1) com.icesoft.util.trackers.RenderDoneTracker.notifyListeners( - locked <0x36c4a013> (a com.icesoft.util.trackers.RenderDoneTracker) com.icesoft.util.trackers.RenderDoneTracker.forceReset( com.icesoft.util.trackers.RenderDoneTracker.propertyChange( - locked <0x36c4a013> (a com.icesoft.util.trackers.RenderDoneTracker) ice.storm.StormBase.firePropertyChangeEvent( ice.storm.StormBase.sendViewportMessage( ice.storm.Pilot.firePropertyChange( ice.pilots.html4.ObjectPool.fireOutstandingImagesEvent( ice.pilots.html4.ObjectPool.fireOutstandingImagesEvent( ice.pilots.html4.ThePilot.onLoadingDone( ice.storm.Viewport$ java.awt.event.InvocationEvent.dispatch( java.awt.EventQueue.dispatchEventImpl( java.awt.EventQueue.access$500( java.awt.EventQueue$ java.awt.EventQueue$ Method)$JavaSecurityAccessImpl.doIntersectionPrivilege( java.awt.EventQueue.dispatchEvent( java.awt.EventDispatchThread.pumpOneEventForFilters( java.awt.EventDispatchThread.pumpEventsForFilter( java.awt.EventDispatchThread.pumpEventsForHierarchy( java.awt.EventDispatchThread.pumpEvents( java.awt.EventDispatchThread.pumpEvents( This appears so be some sort of race condition in the underlying Java icesoft library. It's happened twice in the course of 2 weeks on a new site my client has deployed, but I don't know how to force it to happen on demand.

@{color:#333333}Bradley W, Can you please share the test case?{color}

30620 | April 10, 2019 09:06:47 AM GMT
Amit, not sure what you mean by "test case", it's just a CFDocument tag with a header and footer that turns HTML into a PDF. The only thing interesting i the stack is it seems to imply that the "headerfootdecoration" is part of the issue. The header just had some text inside of <font> tags and the footer just said "Page X of Y". I can't share the exact code as it's part of a govt app and wouldn't run stand alone.

I'll add that I also reviewed some of the source code of the open source version of IcePDF and the deadlock is centered around the synchronized blocks of code in there. I'm sure examining the Java source code of the IcePDF Java library that ColdFusion uses under the hood will help reveal the scenario in which a deadlock can happen. That said, i also acknowledge that IcePDF is a 3rd party library bundled in Adobe ColdFusion and CF11 is likely on an older version of it. Can Adobe comment on what version of IcePDF is in use? I was unable to determine based on how the jar files seem to be "shaded" into the cfusion.jar and not directly placed in the cfusion/lib folder. I'm unclear on whether Adobe has been updating the IcePDF library in ColdFusion 11, or just left it at whatever version was out when CF11 shipped years ago.

Hi Brad,   Does it happen only in CF 11 for you or in all versions of CF? Please let us know the version of CF and the current hotfix number applied to it. Also, are you able to repro it consistently?   Thanks, Kailash
Comment by Kailash B.
30630 | April 15, 2019 10:37:28 AM GMT
Kailash, my client is using CF 11 update 18. They don't have any 2016 or 2018 licenses yet so this code has not been deployed in production on anything other than CF11. After we pushed our new site to production, the issue happened 2 times in about 3 weeks. I have already converted the site to use cfhtmltopdf as we couldn't keep this buggy stuff in production.

We have been getting this cfdocument error on our production server. Only way we are able to resolve is by re-starting the server.

Kailash, we have this issue in ColdFusion 10 and 2016 versions. We are currently migrating from ColdFusion 10 to ColdFusion 2016 so I can confirm that it is a problem in both versions.

Hi Praveen,   Can you share a specific case (I mean the code you are using) after which you start facing this issue?   Thanks, Kailash

30646 | April 22, 2019 07:06:38 AM GMT
Yes, this is a synchronization issue in IcePDF. Adobe can provide you with a hotfix jar to remove this lock. This is most likely a duplicate of my bug . They have fix, they just need to add it to the mainstream release.

We've been seeing this same timeout problem for quite awhile now across CF2016 and CF2018 servers. Restarting the CF instance has been our only solution. I see suggestions above that there may be a hotfix that resolves this. What do we need to do to get that?
