COMPON=GRS-COMMANDS, COMPID=SCSDS, ISSUER=ISGCRET1, POST OF ECB OF COMMAND REQUESTOR FAILED

Component
Global resource serialization (5752-SCSDS)
Issuing module
ISGCRET1
Explanation
An error occurred while ISGCMDR (command router) was attempting to cross memory post the ECB. The ECB was being used by a command requester to wait for a command request to be processed by ISGCMDR.

The areas dumped are PSA, SQA, and LSQA of the command requester's address space, and the command requester's ECB.

Problem determination
Either the ECB address provided on the cross memory post is in error, or the RB address in the ECB is in error.
