Reason
The SMF file sequence numbers are approaching the wrap‑around point of 999. This should not occur and can be an indication of a serious problem on your system. If the sequence numbers do wrap around to 001, CA ACF2 for z/VM issues message ACF426E.
Action
Verify that the high volume of SMF file switching activity is legitimate and not the result of an exec, program looping, or a system problem causing a large volume of SMF recording to take place. If the SMF file switching is the result of a system problem, correct that problem. If necessary, contact CA Support for assistance. If the high volume of SMF file switching is legitimate, be aware of the SMF file naming implications and be prepared to handle this volume of SMF files. You should consider expanding the size of your SMF minidisks to reduce the number of SMF switches on your system.
