IEA808I

Explanation
During formatting of the generalized trace facility
(GTF) trace buffers, GTF encountered a severe error.

System action
GTF ended trace formatting. The system continues
writing the ABEND dump. The formatted trace output is incomplete because
it does not include the most current trace entries.

System programmer response
Proceed according to the response
documented for the error message or completion code that occurred
when GTF ended.
