Products

Issue/Introduction

1. Processes are getting stuck randomly or progress very slowly, slower than before upgrade. Following message is visible in bg-ca.log:
   
   

   ERROR 2024-09-11 09:18:57,295 [Event Handler pool-3-thread-4] bpm.eventmgr (clarity:unknown:session:none) () An error occurred while processing event Event{_messageId='5672721', _objectTypeCode='stepaction', _objectId=5354662, _eventCode='BPM_SAE_DONE', _userId=8, _impersonatedBy=-1, _timestamp=2024-09-11 09:18:56.682, _autoStartProcessed=false, _deleteEventProcessed=true, _pushingEngineProcessed=false} java.lang.NullPointerException: Cannot invoke "com.niku.union.security.SecurityIdentifier.getSessionId()" because "secId" is null

   
   
   
2. Processes that typically finish in less than a minute can all of a sudden take more time to complete.
