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.

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 >>> "Gix, Lilian (CI/OSR) *" <Lilian.Gix@xxxxxxxxxxxxxxx> 09/11/05 12:44:30 >>> Hello, Realy no body have an idea ? :( L.G. -----Original Message----- From: Gix, Lilian (CI/OSR) * Sent: Mittwoch, 2.
