HDMF called to report a case with their HLMS production server that has stopped accepting user connection due to deadlocks.\nUpon investigation, I found few causes of the said problem.\n\n1. E_OP04C0_NEWENUMFAILURE which may be the cause of deadlocks because the query execution plan fails.  We will have to check if this is a bug.\n2. Numerous E_DM9045_TABLE_DEADLOCK on the system.\n3. Still running an old version of patch -- 15683.  We already have 15744 for April 2022 patch update.
