I already tried to :
- Stop Squid, delete swap.state, restart squid
- Stop Squid, format my cache parition, squid -z, start squid
- change cache_dir ufs /cache 5000 16 256 to cache_dir ufs /cache 100 16
256, squid -k restart.
- reboot completely the server

But nothing worked.

Try use my method posted earlier to search for code files. The fact that
your log suddenly shows squid restarting means it died unexpectedly. If
there is a core file it'll be squids problem - if not its probably
something else causing the problem.

Also, you should try clean out your cache_dir potentially... Remove
everything and run squid -z to recreate it

Great, thanks for your answer and questions :

1- I have a message form my browser (IE, Firefox) witch says the proxy
is unreachable. My MSN, yahoo messengers loose their access.
2- Ping like all other services still work perfectly. (SSH, Apache,
Ping,...)
3- Cache.log part is on the previous mail. You can see that there is
nothing special between 09:44:45 and 10:07:05 (when squid come back)

Thanks for help.

L.G.

Lilian

I may have missed earlier entries in this thread so apologies if I ask
you to repeat any info.

1) How do you know squid is unreachable at these times ?

2) try pinging the host squid is running on for a period that covers the
time that the squid is unreachable. Does the host become unreachable as
well?

3) What does cache.log say for these periods ?

I have more thoughts depending on the answers to these

Regards

Mike
