Re: [squid-users] kernel: Out of Memory: Killed process 16482 (squid).

There's nothing useful in cache.log. And I've rebuilt the cache every
time it crack down and then start it again. So I think this can't be a
"dirty" cache problem.

By the way, another box with the exact same config running pretty well
exect that it doesn't run webalizer at 3:00. I notice that this box
always down server miniutes after 3:00, so it may be some thing
relative to the webalizer. I've recommented the line of webalizer in
cron, and see if it will work tomorrow.
