Re: [squid-users] Very high CPU load

check you cache.log. problem can be in cache rebuilding.
if you squid process still used 99% CPU then you must C something in
cache.log and I'm sure it will be cache rebuilding dir that's y it's taking
time. it's depend on size of cache and mem + processor that how they can
rebuild cache fast..

Subject: [squid-users] Very high CPU load


| Hello,
|
| for a few days I have a strange problem with
| squid running under FreeBSD. Although the proxy
| is almost not used squid runs all the time with
| 99% CPU utilization.
|
| Have already rebuilt the complete cache dir and
| installed the latest version (2.5STABLE3) nothing
| changed the situation (rolled back to 2.5STABLE2 again).
|
| Below some information about the system and software.
|
| Did anybody have the same phenomenon or has an idea
| what can be the resaon (or better) the soluion?
|
