System programmer response
 If you suspect an error in DB2, you might need to report the problem. For information about identifying and reporting the
problem, see Collecting diagnostic data.

Problem determination
 Using the SYS1.LOGREC entry and the associated
SVC dump, determine the resource manager module that requested the
execution unit switch. A resource manager should not request deletion
of a service task and then attempt to execute under the same task.
 Collect the following diagnostic items:Console output from the system on which the job was run, and a listing of the
SYSLOG data set for the period of time that spans the failure. 
Dynamic dump, taken to SYS1.DUMPxx data set, by DB2 (04E
and 04F abends).
