This condition occurred recently at a site I support (second time in less than 2 months), where the obvious symptom was in the SYSLOG with a CICS STORAGE VIOLATION - that precipitated SMF 110 subtype 1 (CICS transaction) record flooding for an extended period (up to an hour) - so seeing the spike in CPU-consumption (looping transaction activity) was the first symptom and also there are various REGION/MEMORY metrics in the same data source.
