Symptoms

The system issues one of the following messages when an RRS function is suspended in Logger processing:

ATR248E RRS IS WAITING FOR SIGNAL FROM LOGGER TO RESUME PROCESSING 
                RETURN CODE: returncode REASON CODE: reasoncode DIAGNOSTIC 
                INFORMATION: diag1 diag2 diag3 diag4

ATR249E RRS IS WAITING FOR SIGNAL FROM LOGGER TO RESUME PROCESSING
          LOGSTREAM NAME: logstreamname RETURN: returncode REASON: reasoncode
          DIAGNOSTIC INFORMATION: diag1 diag2 diag3 diag4

The messages indicate that RRS has a suspended TCB waiting for a signal from system logger before it can resume processing. The TCB is suspended for at least 30 seconds. The problem occurs when RRS is in the process of updating an RRS log stream and encounters a temporary error condition. The error condition is identified by the return and reason codes from the IXGWRITE service shown in the messages.

Generally, RRS is holding the SYSZATR RESTART global resource when suspended. The system obtains this resource when RRS updates the ATR.logging_group_name.RM.DATA log stream, which it can do during:

Internal RRS housekeeping
Restart or unset processing

All processing that involves the RM.DATA log stream throughout the RRS logging group (generally the sysplex) is suspended while waiting for the signal from system logger.
