During normal usage, the system may experience periods of time where WP utilization increases and the system begins to perform slower. Review of the logs shows multiple DEADLOCK messages, often referencing the EJPOV or EJPPO tables similar to:
20161129/134018.271 - U00000006 DEADLOCK
20161129/134018.271 - U00003594 UCUDB Ret: '6' opcode: 'EXEC' SQL Stmnt: 'DELETE FROM EJPPO WHERE EJPPO_AH_Idnr = ?'
20161129/134018.271 - U00003524 UCUDB: ===> Time critical DB call! OPC: 'EXEC' time: '3:502.407.499'
20161129/134018.271 - U00003525 UCUDB: ===> 'DELETE FROM EJPPO WHERE EJPPO_AH_Idnr = ?'
20161129/134018.287 - U00000006 DEADLOCK
Further review by the DBA may show the deadlock request referencing itself in a Page Lock.
