i am using squid 3.1.19 for testing and will use in the next couple days
squid 3.2 because it has couple new icap options.

i have added some caching to my icap server and the stress tests shows
efficiency of about 4000 requests per second.
a unlimited linux FD to support the stress testings to 65535 for squid
and my server.
it is double handling connections to mysql and redis while redis is a
persistent connection and mysql not.
mysql requests done only and only if redis dosnt have the data needed.

so when im testing squid.. using apache benchmark after about 2000
finished connections squid stops passing icap requests like a "failed"
ICAP service until the recovery time(30 secs).
i have set the bypass on the icap service to on to allow the stress test

so squid continues to serve the requests but will stop icap queries.

any direction on what to look for?
