The command did not complete because it did not exclusively obtain the SYSZMCS.MPFTABLE resource. This is most likely due to a SHARED request (that is, a WTO) not completing its execution.
The system rejects the command.
Issue the command again. If the command continues to fail, issue a DISPLAY GRS,C command and check for contention on the resource.
