Error Message : ORA-00060: deadlock detected while waiting for resource
A problem has been solved where deadlocks occured during workflow execution if tasks within the workflow have MAX_PARALLEL restrictions set.
Further technical details: When a workflow with several parallel task has been started , several EXEC_LOH messages were send. The deadlock occurs in the QUITT2 message for GENX that was send by one of the earlier EXEC_LOH messages. While the QUITT2 message is processed, one of the other EXEC_LOH is also processed and that is resulting in a deadlock.
The following server routines can be found in the logs of the WP´s: JPEXEC_R/EXEC_LOH JPEXEC_R/JPENDE / JPEXEC_R/DEACT JPEXEC_R/QUITT2
