Issue:

The DE Manager fails due to an java.lang.StackOverflowError error condition. This may cause the DE Manager to fail over to the Standby server if running in an HA configuration. Otherwise, the Manager fails and will need to be restarted.

Environment:
CA Workload Automation DE r11.3.x
Cause:

20170530 18:28:01.382 [essential] [ERROR] 911-Service: The cause of the server shutdown: 

java.lang.StackOverflowError

The server encounters this error due to the Java Heap and Stack reaching or exceeding the limit defined by the MAX_HEAP_SIZE and STACK_SIZE parameters in the startServer script for the DE Manager.

Resolution:

If your server has the memory available to increase to satisfy increasing the MAX_HEAP_SIZE and STACK_SIZE parameters, then increase these parameters by either doubling or tripling the value. MAX_HEAP_SIZE cannot be increase above 2048MB (2GB) if running 32-bit DE. If running 64-bit DE, MAX_HEAP_SIZE can be increased to as much as your system can accommodate.
