D0D

Explanation
The system abnormally ended a subtask. While processing
the subtask's end, the recovery termination manager 2 (RTM2) was reentered
incorrectly. Therefore, RTM abnormally ended all tasks in the job
step.
Note: The original abend code is in the supervisor request
block (SVRB) for the original SVC 13 (ABEND macro). This SVRB is queued
from the task that experienced the original error.

System action
RTM2 attempts to end the job step. The system
may write an SVC dump, or the program may write an ABEND dump. The
system sends messages about the problem to the job log.

Operator response
If the system programmer asks for an SVC dump,
set the following SLIP trap: SLIP SET,COMP=D0D,ACTION=SVCD,END

System programmer response
  Do the following: If a dump is not produced with the abend, ask the operator
to set a SLIP trap to obtain an SVC dump.
Examine the abend code for the original subtask. This
abend code can be found in the SVRB of the original SVC 13 SVRB queued
from the task that experienced the error. Continue diagnosis for
that abend code. If the problem cannot be resolved, continue with
step 3.

Look at the messages in the job log.
Search problem reporting data bases for a fix for the
problem. If no fix exists, contact the IBM® Support
Center. Provide: An ABEND or SVC dump
