Checkpoint file has too many updates outstanding.
This error occurs when there are too many updates pending for a checkpoint file.
Application Performance Analyzer STC terminates with a S0C3.
Verify that all Application Performance Analyzer STCs with the same sysplex group name (SPXGroupName=xxxxxxxx) have the same checkpoint file defined in their CONFIG files. Also verify that the checkpoint file has not also been defined in a CONFIG file to a non-sysplex Application Performance Analyzer STC. Once the CONFIG files have been corrected, bring down and restart all Application Performance Analyzer STC's.
