The generalized trace facility (GTF) is ending because it has detected an error condition. If message AHL031I has not been issued, then the ending condition is usually a programming logic error and the system write an SVC dump. If message AHL031I has been issued, then either a message with additional information about the error precedes AHL007I or a dump is written.
The system abnormally ends GTF, issues other messages, and request an SVC dump.
If message AHL031I has been issued, restart GTF.
If message AHL031I has not been issued, search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the SVC dump, if available.
