Apache2 Freezes

[celtic]

My ISPconfig v10 is working fine but sometimes and without any known pattern all websites come offline and inspite the server is up the only way to put thinks back in order is to stop and start Apache service.

This can be very serious since I cand diagnose the cause and sometimes the websites are offline several hours.

Can anyone help me troubleshoot this issue~?

Kind regards and thanks in advance

I also have this issue occasionally.

Celtic, are you using ISPconfig?

One of my reasons to switch to ISPConfig was the ability to use the Apache webserver version I wanted, because I experienced the same problems with DirectAdmin. Apache on my previous servers always core dumped. I had a cron job watching the log files, which restarted apache when it found an error.

I also switched from Redhat to Ubuntu and this last change seems to be the best choice I even made. I do no have any problem with apache anymore. I do use the distrubution version, as the manual compiled Apache on Redhat was the one giving problems. I know this statement doesn't help solving your problem. Which distro are you using?

I am using ISPCOnfig 2.2.10 under Ubunto 6.06.

Don't know my Apache2 version because my linux skills are very poor.

I've had the idea of creating a script that restarts the service from time to time to put order in my server but that wont solve the issue just minimizes the damages.

Help is appreciated.

To find your apache version

httpd -V

. I'm running Ubt 6.10.

Are there any errors in Apache's error log?

In my webadmin Apache2 is not configured (???) so can anyone tell me what file to watch and post?

[falko]

What's webadmin?
Are there any errors in Apache's error log?

[celtic]

Sorry... Its not webadmin but webmin.

Anyway... My error log manages to collect 11 Mb of data in one week so it probably has some issue pending.

Attached is the error log from 9th March till now and we had a breakdown yesterday.
