DFS3928W UNRECOVERABLE ERROR DURING IMS DUMP REQUEST MAY RESULT IN NO OFFLINE DUMP.

Explanation
 IMS SDUMP processing stopped because
problems were encountered during request processing in IMS SDUMP.
If a memory dump was not already produced, no memory dump is created.

System action
 DFSFDMP0 returns to the issuer of DFSDUMP with
RC=8. Alternate online diagnostics, such as spin-off memory dumps,
software LOGREG entries, and dependent region memory dumps, are allowed.

Operator response
 No immediate action is necessary, but tell
the IMS system programmer that you received this
message.

System programmer response
 Examine the diagnostic output, including
the LOGREC entries created for the memory dump processing errors,
to determine the cause of the problem.
