Users encounter multiple issues when working in their applications, including screen freezes, blank screens, and random errors in different screens.

Error Messages

javax.ejb.EJBException: nested exception is: Save, Delete or Commit has failed because lock is not held

Root Cause

CAVerticalLogTaskCompleted activity is configured to execute on close of the Process tab. This event-based asynchronous activity happens in parallel with the PRPC work item Close and Flow End calls. At the end of the flow or on close, PRPC releases the lock on the work page. (In the case of RunOnInteraction service processes, it releases the lock on the interaction page.)
The reported issue comes when the PRPC work item closes before the CAVerticalLogTaskCompleted activity is executed.​
