Explanation
A system error, uncorrectable machine error, or
error that cannot be determined occurred under one of the following
conditions:
- While the system was attempting to satisfy a request made through
the STORAGE macro
- While the system was trying to process an RC, RU, VRC, or VRU
form GETMAIN macro
- While the system was trying to process an RC or RU form FREEMAIN
macro
A reason code in the SDWACRC field of the system diagnostic
work area (SDWA) explains the error:
Note: Some VSM return codes
may be a half-word in length. In these cases, the high-order byte
is the module id of the issuing module, and the low-order byte is
the return code.

- Explanation
- 01
- While attempting to free storage, the system tried to release
central storage backing global or local system queue area (SQA or
LSQA) storage. A program page fixed the virtual storage. However,
it is a basic property of the system that SQA and LSQA storage is
page fixed.
- 02
- While attempting to release an entire LSQA subpool, a service
routine was called to free storage described by an allocated element
(AE). The service routine returned a return code indicating that
the storage is not described by an AE.
- 04
- Status information indicates that the system has obtained a global
lock in support of a request to release storage. However, when the
system attempted to release the lock, the release request failed.
- 08
- While attempting to obtain storage, a storage management service
routine returned an incorrect return code to the virtual storage manager
(VSM) interface module.
- 09
- While getting or freeing storage in a local or global system queue
area subpool, the service routine that builds double free elements
(DFE) tried to place virtual storage on the DFE queue, but could not
do so because the storage was described by another DFE already on
the queue.
- 0C
- While attempting to free storage, a storage management service
routine returned an incorrect return code to the virtual storage manager
(VSM) interface module.
- 10
- While in recovery processing, the system detected a condition
that is normally considered a user error. However, it is not likely
that the error is a user error because recovery processing is in control.
- 14
- VSM failed to backout the acquisition of a new address queue anchor
table (AQAT) stack. In this case, the system issues abend X'778' only
to record the error. The system continues processing upon retry from
VSM recovery.
- 20
- The STORAGE service routine has failed unexpectedly. The failure
is probably not a user error.
System action
The system writes a logrec data set error record.
The system continues processing.
System programmer response
Search problem reporting data bases
for a fix for the problem. If no fix exists, contact the IBM® Support Center.
Programmer response
Run the job again. If the error recurs,
contact the system programmer.
