My suggestion is to check and see what cron jobs are running: cat /etc/crontab or (as root): crontab -l and then crontab -l any other users that might be running cron jobs If there's a timely pattern to the connectivity issue, the root of the problem probably has something to do with a schedule for something.

Re: AW: [squid-users] Squid unreachable every hour and 6 minutes.
The disk space is over limit error is not saying the disk is full. The cache has reached the limit that's been set in the squid.conf file. It could be causing squid to die, but how likely is it that this would be the cause, if squid dies 6 minutes after every hour? My suggestion is to check and see what cron jobs are running: cat /etc/crontab or (as root): crontab -l and then crontab -l any other users that might be running cron jobs If there's a timely pattern to the connectivity issue, the root of the problem probably has something to do with a schedule for something. Cron would be a good place to start. On the disk space is over limit issue... You really shouldn't have to tend to this. Squid should use whatever replacement policy was specified at compile time (forget which one is default if none is specified) To remove old/unused cache objects in an effort to free up space. However, if squid is trying to do this, and is actively handling proxy requests at the same time, squid could be running out of resources. What specs do you have on this machine?

Please repeat that again. (1) stop squid (2) find out wht are the cache directories squid uses, for example # grep cache_dir squid.conf cache_dir ufs /data1/squid_cache 6000 32 512 cache_dir ufs /data2/squid_cache 1 32 512 # In this example /data1/squid_cache and /data2/squid_cache are the cache dirs. (3) Clean all cache dirs - in this example: cd /data1/squid_cache rm -f * cd /data2/squid_cache rm -f * (3) create the cache structures again: squid -z (4) Start squid. What happens? Is squid running? ps -ef | grep squid What does cache.log say since starting of squid? Is squid reachable? (5) What happens after 1 hour an 6 minutes?

Try use my method posted earlier to search for code files. The fact that your log suddenly shows squid restarting means it died unexpectedly.

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. From: Mike Cudmore [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 9.

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) * [EMAIL PROTECTED] 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.
