These are difficult at best. Whatever failed to happen has already been

hung up with ‘‘DUMP’’. Use the SLUIPCS PRINT command with the
‘‘COMM TASK PTTE IOS’’ options to see what was happening in each
job/task when the system went into the wait. Check the SLUIPCS PRINT
listing for devices with outstanding requests (Count field in DEURQST is not
equal to 0).
