[squid-users] Squid Memory Usage

Hi,

I was wondering if you guys should shed some light on the memory usage
of my Squid setup. When I use the cache manager it is showing the
following stats;
StoreEntry 48 5515048 258518 258520 0.01 66
5515048 258518 258520 100 0 0 0 0 0.00 0.00

When doing a top on the unit Squid is using 600mb+. It reaches 1500mb
usage in 4-5days and then dies.

Here is the memory settings from my squid.conf

The timeout settings are all low, there are no custom refresh
patterns, and I am using squidGuard as a helper with 40 children. The
unit is doing about 30RPS which the hardware is definitely able to
handle more than double this.

The cache drives are full and the cache has been in place for a few
years now. We are running Squid 2.6 stable 18.

If the cache drives are full, when squid starts is that not the memory
it should use and hover around that mark? I understand that it will
change but it grows rapidly and then dies.

Please let me know if there is anything more I can give you to help with this.

Thanks in advance,
Darryl
