Hello everybody, I have a problem with squid server, in the morning at the same time, every machine on our local network can’t have access to Internet and I have therefore to manually restart the computer on which squid is installed to make Internet accessible again. I have found following in /var/log/daemon.log at the time when the connection is interrupted: Feb 18 06:25:58 localhost squid[3501]: storeDirWriteCleanLogs: Starting... Feb 18 06:25:58 localhost squid[3501]: Finished. Wrote 8952 entries. Feb 18 06:25:58 localhost squid[3501]: Took 0.1 seconds (171787.1 entries/sec). Feb 18 06:25:58 localhost squid[3501]: logfileRotate: /var/log/squid/store.log Feb 18 06:25:58 localhost squid[3501]: logfileRotate: /var/log/squid/access.log Feb 18 06:25:58 localhost squid[3501]: helperOpenServers: Starting 5 'ldap_auth' processes Excepting this trouble, squid seems running fine. Is there something in squid.conf I should be changing to avoid this problem? Thank you for giving me any suggestions. Bye!
That is just a log of squid starting, you need to go through the logs to see exactly why squid dies, it is usually something to do with the OS not squid itself but in your case it does not seem like its disks being full.
Thanks for your suggestion, but I have already looked at the contents of the store.log and access.log in /var/log/squid/ but I've found noline telling why squid die. I have found following in /var/log/squid/cache.log at the time when the connection is interrupted too: 2008/02/18 06:25:57| storeDirWriteCleanLogs: Starting... 2008/02/18 06:25:58| Finished. Wrote 8952 entries. 2008/02/18 06:25:58| Took 0.1 seconds (171787.1 entries/sec). 2008/02/18 06:25:58| logfileRotate: /var/log/squid/store.log 2008/02/18 06:25:58| logfileRotate: /var/log/squid/access.log 2008/02/18 06:25:58| helperOpenServers: Starting 5 'ldap_auth' processes In the other hand, I've looked at the processes and I found this: dansgua 18261 0.0 3.8 21556 19724 ?

S 06:25 0:00 /usr/sbin/dansguardian Is it in relation with? Thank you for helping me.
If you are running on a redhat like system check /var/log/messages if a debian like one then /var/log/syslog, Yes the dansguardian processes are used by squid but are not capable of killing squid, unless of course they are taking up all the system memory. Next time the squid fails dont reboot the box check the conditions on the box at the time try restarting squid itself and see if it can start if there is a system problem it will not start but it will issue out an error message. Rebooting the whole box seems to clear the system problem which means you dont get to the bottom of the issue.
Thank you for your suggestion but I've already done that using: # crontab -e 30 6 * * * /etc/init.d/squid restart This command makes squid restarting itself at 6h30 after the interruption at 6h25, but Internet is still inaccessible. And this morning I have found this following in the /var/log/syslog (debian) just after the interruption as first line: Feb 23 06:26:18 localhost syslogd 1.4.1#17 : restart
