Requestors are building up
SA-33570
Summary
The user has a Service Package EJB called PolicyChangeRequestEJB. Pooling is set to
Min Idle = 5
Max = 25
Wait time = 5
But the requestors are exceeding 25. Currently, after 4 days of running, one servers is at 139. Their Service EJB runs "Execute asynchronously" using a request Processor. If he changes it back to "Execute Synchronously", it behaves correctly. This has been happening since we upgraded.
Error Messages
Not Applicable
Steps to Reproduce
Run the service package on several different environments.
Root Cause
The configuration of WebSphere Work Manager for the Pega instance was setup with "Work request queue size" of 5000. Pega recommends value of 0 so that the queue size is managed automatically. Large values can cause significant performance issues.
Resolution
Reconfigured setting to 0.
