Not able to change the thread pool size

Getting “Available Thread Pool Threshold No Longer Exceeded”. Could see continuously in server log. I tried to increase the watt.sever.threadpool size from 75 to 300. But after restarting the IS the change is not reflected. i.e I could see only watt.server.threadpool=75 not 300. IS is assigning to the default value back.

Anyone faced the same challenge? what could be the root cause?

Hi Lance,
Did you try changing it from IS admin console ---->Settings—>Resources —> Server thread pool ?

Actually i normally do it from here and it worked I never faced issue which you got but you can try changing it from resources under settings.

Try doing this from IS admin page Settings->Resources -> Server thread pool.
