The connection limit sounds like a good hint. You might want to keep an eye on the number of flows to that vip using FLOWTABLE::count to log that also.

Maybe you could count the connections on that VS and in whatever TMM is used for that flow:

log local0. "LB_FAILED! info: [event info] , current conn in this TMM: [FLOWTABLE::count], current conn in vs [virtual name]: [FLOWTABLE::count virtual [virtual name]]"

 

Do you see any other /var/log/LTM error logs like SNAT pool exhaustion or the like?
