078

Explanation
There was an error in one of the following routines
invoked by the region control task (RCT): ATTACH of the dump task
ATTACH of started task control (STC) during RCT initialization
PURGE I/O during QUIESCE processing
The real storage manager (RSM) swap out routine during QUIESCE
processing

 RCT received an unacceptable return code from the routine and
cannot continue processing. This abend may indicate a storage shortage.

System action
The system gives RCT recovery control. The system: Requests that the address space end
Issues an SVC dump for the address space if the error was unrecoverable
or recursive
Writes a logrec data set error record
Performs resource clean-up

System programmer response
Look for errors in the logrec data
set error record or the SVC dump indicating a prior failure in the
same address space. Search problem reporting data bases for a fix
for the problem. If no fix exists, contact the IBM® Support Center. Provide the logrec data set
error record and the SVC dump.
