ACE Total Connections Failed stats

Question

I have been monitoring connection stats on an ACE Module context (show stats connection).
During recent load testing I observer that about 1/3 of all connections were failing and some timing out.
How can I find out more details about the connections that are failing and timing out?
ie which specific connection are failing, what type of failures increment this counter, etc
Cheers,
Karl

Hi Kim,
Thanks for responding.
A load test was run earlier today. I cleared the counters and collected some stats (see below).
I also had a look at various other stats for drops.
As far as I could see all relevant, rservers, serverfarms and service-policies were:
in service BUT
drop stats were not incrementing at anywhere near the same rate as the Total Connections Failed stat.
Another load test is scheduled for tomorrow.
Any thoughts on what to check next?
