it depends what you mean by loops. if the loops are generating actual cics abends, then you can trap those in AO. the CICS/AO feature also lets you set thresholds for the number of allowable abends within a period of time. However, a real CICS loop will not abend nor be detected by the ICVR interval nor would it necessarily create a short on storage condition. But it may use up alot of cpu time which the AO health checking feature might catch if the loop slows down the region enough so that no response is given to health checking within the required interval.

It's not my code but I must have got it from someone on this list but I don't know the legality of passing it on.
