Dear Tim/Neil,

I will look up the details and send it over to the group. The messages and the cache.log looks normal. The access.log is not set, i.e. /dev/null. I also realised that as soon as number of users are high, i.e. when I start redirecting (-j REDIRECT) more users to Squid, it starts crashing, but if I keep 2-3 IPs then it's not a problem.

It does look like an OS related issue from the details from Neil, however, if I don't use squid i.e. no -J REDIRECT then the server keeps running for months, but as soon as I turn on the REDIRECT, it starts crashing almost every week.

Maybe I keep a strace on squid and dump the data and also keep the vmstat 5 dumping data so that I can co-relate and come up to some conclusion.

I wanted ideas on what to trace so that the root cause is identifieid. Maybe it's a hardware problem but due to the fact that it only shows up after I turn on squid, its is difficult to justify the need for different hardware.

Thanks in advance.

Regards,

Mitesh

Squid is not hooked into the kernel. IPTables is. I would posit that to be the source of your trouble. You stated that you are on a satellite link, which means your are going to have a higher number of open file descriptors. Perhaps IPTables is "running out" and causing the kernel to hang (complete conjecture).

For what it's worth, I have a number of sites on satellite links, but I don't use interception.
