Error description

  • You are formatting CICS Trace and find that eventually you
receive an S80A ( ABEND80A ABENDS80A ) abend. Examining an SVC
dump of the situation shows that a buildup of storage in
Subpool 0 Key 8 ( SP0 KEY8 )
CICS has obtained duplicate 32K buffers, but only done a
FREEMAIN on one of them.
They may be more prevalent when using vendor products which
examine and format CICS trace from within a running CICS region.
.
