APAR status

  • Closed as program error.

Error description

  • CSQ3009E was issued  and was followed by the abend
ABN=378-00000018 .
The abend occurred when attempting to free 0x48 bytes of key 7
storage while running in PSW key 0 with a CALLRKY=YES STORAGE
RELEASE from subpool 229. SYSTRACE shows a previous
S052-00000512 abend while in an ETCON from CSQ3RRSX which was
retried by CSQ3RRXF to CSQ3RRSX.
This problem is a regression caused by APAR PH40928 .
This  APAR will also contain the fix code from APAR PH50169.

Local fix

  • Return to the previous level without PH40928 ( UI82339 - MQ
V9.1 / UI82338 - MQ V9.2 ).
Note: The problem is in the base code for MQ V930, so there is
no fix which can be removed to circumvent it.
