After the fact may be more difficult. But the things I would do are: 1) See if there might be any SVC Dumps taken during the time. They may contain information on GRS even if the dump was not specific to this issue. 2) See if there are any LOGREC data produced. Sometimes yes, Sometimes no. 3) Look in SYSLOG (OPERLOG) during the time the Contention messages are produced on both systems. See what batch jobs or other issues might be happening at that time. Sometimes you get lucky and see a process that will give a clue to the issue.
Otherwise, definitely put in automation processes that get triggered on the messages you saw and do the D U and D GRS commands. You may also wish to do a F CATALOG command to list the tasks currently in process in the automation. It may show what is being held in the CAS.
