An error occurred during allocation processing. The ESTAE routine IEFAB4ED performs general recovery processing and requests an SVC dump (if no SDWA exists). If an SDWA exists, additional checks on the error are made. An SVC dump is then requested if the error is not a user error and one of the following occurred:

The areas dumped are LPA, ALLPSA, SQA, TRT, SUM, SWA, and LSQA. Key control blocks used by allocation are included in the summary list in the SVC dump.
