Problem Description:
IIS worker process (w3wp.exe) hangs with multiple threads in the wait chain after making a configuration change to the site in IIS manager.

Steps to Reproduce:
Create two sites in IIS, "Site1" for public site using FQDN and "Site2" bound to (to be later configured for administrator site).  No other IIS settings are configured.  Install ColdFusion 11 standard using secure profile on separate partition and specify to install for "all" IIS sites.  After CF has finished installing and confirmed Administrator site works correctly on Site2, test simple web webpage to confirm service is also working for Site1.  A w3wp.exe worker process will be started for Site1.  Now make a change in IIS for Site1, such as adding a MIME type.  Now try to reloading the simple webpage on Site1.  The browser will wait trying to load the webpage forever.  In task manger, right-click the w3wp.exe process for Site1 and choose Analyze wait chain.  There will be a child thread on the tree for that process. Try refreshing the browser again and another thread (or two) in that tree will be waiting.  If the worker process is killed while the browser is waiting to display the page, a new worker process is created and the browser will display the page.   Otherwise, the browser will eventually time out and the worker process will never recover.  

I have replaced the existing isapi_redirect.dll with the one that addressed the slow startup time per bug #3758172 and the issue with the worker process hanging still exists.

Actual Result:
Worker process hangs on configuration change.

Expected Result:
Worker process should continue to function.

Any Workarounds:
Killing worker process allows the server to recover but this is not acceptable.

This is in regards to this bug incorrectly marked as fixed. I do not understand why you need votes if you know it is not working.

This is still an issue. I don't see any reason for this resistance to have this issue fixed. How are we to address our customers (who purchased this product) when they say that this is a problem and want it fixed?

Anit, I just wanted to advise that this issue is not apparent in any way on CF10. Maybe comparing what may have changed in the connector might be helpful .. no idea really just thinking out loud.

I have found this issue in CF 11 running on 2008R2 and IIS7. Restarting IIS works faster than recycling the site in the app pool but is unacceptable. I hope Adobe addresses this promptly.

This bug appears to have been introduced in CF11. I could not replicate in 9 or 10. I also agree that a vote is ridiculous. This can be a showstopper for unsuspecting site owners. This BS disrupted several production sites and has cost me hours of testing and workaround attempts. It's not what I'd call a "feature!" I now have to make setting changes at 2AM to avoid site stoppage. Unacceptable. Please stand up and fix this.

What updates!? There haven't been any public updates since I installed CF11 a couple months ago... still haven't put this into production because of this bug. :(

This is highly irritating on a dev server where you may be tweaking the IIS config frequently. The only "solution" that works for us is killing the worker process every time we make a trivial change.

Hi, we want to update the webserver for our customer. I've told him, we're buing the newest server software to be save for the future. I'm sorry that I have to say him, that the new software won't work. Please fix this bug as soon as possible. Thank you...

I vote too because nothing happens since 2 month. You should change your system requirements to "Windows 2012 not supported" so that new customer don't buy a Software that don't run at Windows 2012.

Just replaced the DLL per the instructions and this bug is fixed but a new, bug has been introduced... a total show stopper. Posting a form doesn't work!. Try creating a very simple form and posting it. You'll get a 404 page not found. I guess I'll submit another bug ticket....

This dll massively screwed up my website. IIS is throwing 404's on pages that I'm looking at right in the directory -- files that have been working for years. Rolling back...dreadful

@mkranitz, sounds like you're missing the virtual 'jakarta' directory, which is needed for pointing to your cf connector. Also, this fix has been included in update 1 for cf11. Everything is working fine here =)
Comment by External U.
11898 | November 12, 2014 04:53:47 AM GMT
No I'm not. The system worked before I replaced the DLL and then once again when I rolled back. The CFIDE and JAKARTA dirs were there all along

You could try to just install update 1 (which includes this fix) via the server update menu in your CF administrator. No need for this individual hot fix.

I know. I am a bit hesitant because I have 6 sites that depend on the update working properly.

Can someone please comment on whether the latest update for ColdFusion 11 does, in fact, fix this issue?
