Created: 04/04/2016

Components: General Server, EFR

Versions: 11.0

Failure Type:

Found In Build/Fixed In Build: CF11_Final /

Priority/Frequency: Major / All users will encounter

Vote Count: 4

Listed in the version 2016.0.02.299200 Issues Fixed doc
Verification notes: verified_probably_fixed on July 08, 2020 using build 2016.0.02.299200
Problem Description: Coldfusion administrator states that for a Standard Edition server the number of concurrent cfthreads is limited to a maximum of 10. However after testing this it appears the maximum available concurrently is only 2. 

Steps to Reproduce: On standard edition server log in to administration and go to request tuning. Under the "Maximum number of threads available for CFTHREAD " section change maximum thread count to any number higher then 2. Create multiple cfthreads and view the number of "Running" threads at one time. The number is never greater then 2 irrespective of the value entered on the administration screen. Included test files to demonstrate issue. Open cfthreadtest.cfm which launches 10 threads and redirects to a view of the status of all threads.

Actual Result: Only 2 threads ever execute at a time. 

Expected Result: The number of threads running should match the maximum number entered through the administration up to 10.

Any Workarounds: N/A

Nimit is this fix going to be included in a Coldfusion 11 update as well?

This needs to be resolved for ColdFusion 11 as well. This is affecting our team.

So I do have a question with this “fix”. Did the CF Team fix it to allow 10 cfthreads? Or did they “fix" the CFAdmin page to show there’s only 2 cfthreads allowed?

Hi Nimit, +1 to Alan's and Wil's questions: 1) Will CF11 get the fix? 2) Does the fix increase the limit to 10 threads? Thanks!, -Aaron

I would suggest bugs should NOT be closed until you can provide the "Fixed in Build" information. If there is no fix in the wild, it should not be closed.

Hi Nimit/Adobe, +1 to Mary Jo's statement/request. Bugbase's search form doesn't work properly wrt Fixed In Build. I've just filed 4150968 for the same. Currently, only THREE tickets are returned when searching for tickets Closed/Fixed in CF2016. And searching "CF11" only returns 136 tickets (you can trust me that count isn't correct either). Thanks!, -Aaron

+1 to Mary Jo. Glad this fix is finally coming. Was it as simple as: <cfif $ GTE 10000> <cfset threadcount=10> <cfelse> <cfset threadcount = 2> </cfif>

So is there a reason the "Fixed in Build" field still isn't updated? Seems like you all just don't even use that anymore.
