An error occurred during GTF processing when AHLMCER attempted
to route the MC (monitor call) interruption to its affiliated FGBR
(filter, gather, and build routine). The FRR routine (AHLMCFRR) requests
the dump prior to attempting retry. The MCRWSA and SDWA are moved
into the SDUMP buffer. AHLMCER is included in the dump as part of
the storage dumped. GTF ends. The areas dumped are SQA, SDUMP buffer,
failing module, and failing address space.
Associated problem data
Message AHL007I is issued.
Problem determination
This error is usually an inability to pass control to an FGBR because
of changes to the FGBR in SYS1.LPALIB. Field MCREID in the MCRWSA
contains the event identifier of the HOOK that GTF was processing.
