Hi,

We run a large ISP in New Zealand and are having TREMENDOUS problems with our Cache server.. (Squid Version 2.2 under Redhat Linux 6.1)

The machine we have squid operating on is a Compaq with the following:

1GB RAM

Raid 5 Array with 5 x 18GB 20k seek SCSI drives in them

Raid Controller has 256MB RAM

Dual P700

Dual 100BaseT Ethernet Cards

We find that when we pass a fiar amount of traffic through them Squid keeps running but slowly stops serving pages to anyone.. Eventually it stops running and leaves no comments in the error logs as to why. Both of the machines that we have do this...

We have a VERY generic Squid configuration with no fine tuning and it KEEPS doing it... We have tried squid on a smaller machine with less traffic but it does it as well.

We have a layer 4 switch that sends only HTTP requests through the Proxy (although to do this for some reason the Proxy has to be set up to transparently cache everything) that was supplied by Alteon (a Alteon Cache Director) ....

Do you have any ideas? Do you have any idea as to the OPTIMAL configuration for Squid under this scenario (as in the details in the config file that I should utilise)??? What version of squid should I be using?? Any patches that I should apply? Any comments on the file structure that I should look at implementing?

Your help would really be appreciated!!
