The CA Workload Automation predefined (canned) report failed with a java error "GC overhead limit exceeded"; it was seen in the server's tracelog file and the report's log.
The Java process that generates reports on the server ran out of java heap memory most likely reason is the volume of the report's data retrieved.
By default, the server allocates 512 MB to the Java process that generates reports on the server. If you get a Java heap space or out of memory error in the console while running a report, allocate more memory to the report process. For example, you can increase the maximum memory available for generating reports to 1024 MB.
Follow these steps:
Connect to the server as an administrator using CA WA Desktop Client.
NOTE- Restart of DE scheduler is not required.
