IIS7 application pool spawning worker processes
- by scott_lotus
IIS7
ASP.net 2.0
Number of worker processes growing out of control in single app pool. Appear to keep spawning upwards.
Monitoring the w3wp.exe process i can see "current connections" to web service sometimes spawn out of control but not always , only worker processes are consistently growing when this issue occurs.
Number of worker processes normally 0 - 20 , when spawning they can reach 1000 +
This was deployed in:
%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet.config
maxConcurrentRequestsPerCPU="50000"
maxConcurrentThreadsPerCPU="0"
requestQueueLimit="50000"
But issue still occurs.
Have tried running PROCDUMP on the exe process but the mini dump isnt a great help.
I understand this is 99% probable an app issue , what i need help with is tracking it down.
Thank you for any tips.
Scott
