Error description
The 0C4 in CSQVSRRX can occur during shutdown when a service task (in this case the trace task, TRTASK00) is not ended during normal shutdown processing. This is detected by CSQVASTM during local memory terminate processing, so CSQVDST0 is invoked to ABTERM the service task with 6C6 and reason code 00E50070. CSQVSRRX is invoked under the service task TCB to process the abend, and tries to access the RMFT. However, the RMFT has been released at this stage in shutdown processing, so the 0C4 occurs. ADDITIONAL SYMPTOM : ABEND5C6 00E501A1 ABEND0C4 ABENDS0C4

This is detected by CSQVASTM during local memory terminate processing, so CSQVDST0 is invoked to ABTERM the service task with S6C6 and reason code 00E50070. CSQVSRRX is invoked under the service task TCB to process the abend, and tries to access the RMFT. However, the RMFT has been released by this stage in shutdown processing, so the 0C4 occurs. The root cause of this problem is that the TRTASK00 is not being ended correctly by CSQWVZCT.
Problem conclusion
The code was changed to correctly end the TRTASK00 task in CSQWVZCT and to suppress the 6C6-00E50070 logrec entries. 100Y CSQVASTM CSQWVZIT
