Error description
You are experiencing CICS shutdown hang issue. CKAM is running in QR TCB. . QR TCB's IRB PSW points to CSQ3ID80 UI23984 which issues a wait. MQ domain shows the following, Connection status: Quiescing In standby mode: No Mqname: xxxx Qmgr: xxxx WebSphere MQ release: 0800 Initiation Queue: API Crossing exit active: No Date/time connection completed: dd/mm/yy 14:37:29 Date/time disconnection completed: dd/mm/yy 14:51:20 . Dump time: dd/mm/yy 14:54:52 . CONTENTION EXCEPTION REPORT JOBNAME=yyyyyyyy ASID=nnnn TCB=00B99988 JOBNAME=yyyyyyyy HOLDS THE FOLLOWING RESOURCE(S): RESOURCE #0001: There are 0019 units of work waiting for this resource NAME=MAJOR=SYSZCSQ3 MINOR=CSQYALLI SCOPE=STEP Further diagnosis found that when CICS is shutting down, CICS TS 5.2 DFHMQDSC issues a QRPL_ENDCTX request to force all CICS TCBs to disconnect from the queue-manager. This processing involves an IRB being scheduled on each connected TCB which will issue a Terminate Identify request. CSQ3SSI2 requestes the SYSZCSQE / CSQYALLI ENQ, and as it was not immediately available it waited on the supplied ECB. However, the ECB will never get posted(the ECB for CSQ3SSI2 had been posted by the time the dump was taken).

Additonal keywords: CSQY291E CSQWDSDM
