Error description
Customer complained that as RRS came back up, the broker region was hanging after RRS restart. For instance,WMB broker region was hanging when RRS was killed. By issuing MVS CANCEL command to simulate RRS failure, EGs could be terminated but broker region was hang after RRS restart. It is because MQ Get-waiters using an RRS stub (such as IIB) will never be posted after a restart of RRS. Additional Symptom(s) Search Keyword(s):

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: RRS applications issuing MQGET with * * MQGMO_WAIT hang if RRS is restarted * * while the application is waiting to be * * posted. * **************************************************************** * RECOMMENDATION: * **************************************************************** When RRS is restarted, any active RRS agents are driven through End of Task (EOT) processing. This should result in any such agents that are in an MQGET wait being posted when the handle is closed, however an incorrect check in CSQM1P1W causes this post to be incorrectly skipped.
Problem conclusion
CSQM1P1W is changed to no longer skip the post when an RRS agent is driven through EOT. 000Y CSQM1P1W
