I think that the DB2 messages in this case are generic for 'the stored proc failed'. Were there any other messages in the JES log? You might find the messages at the very top of the WLM sysout. You'll also want to check the compile listing to see what's going on right around offset E49C. You probably have a typical failure like a S0C7 and the WLM is confusing the issue because it's displaying it's messages in addition to the messages for the program failure.
