Apache2 constantly crashing

[hendry]

HELP! My Apache2 is constantly crashing. When logging in to the adminpart of ISPConfig I see the service is unavailable. I can restart it from the shell and then it runs again for a couple of minutes. What can it be? Running on the latest stable version (just updated it in the hope it would fix something) on a Suse 10.1 VPS server at Strato. Is there a place where I can find the reason of crashing? Cannot find it in the apache errorlog

Please have a look at the apache error log under /var/log/... and in the error logs of your websites. Also have a look in the messages and syslog.

As your server is a VPS server, it might be that you just reached the limits. Have a look at the beancounters (if your vps is a openvz or virtuozzo system) with:

cat /proc/user_beancounters

Do you have any failcnt?

On Debian the log files for Apache are within:

/var/log/apache2/error.log
/var/log/apache2/access.log

I guess for Suse it is something like that too.

You can follow what's happening with the commands:

tail -f /var/log/apache2/error.log
tail -f /var/log/apache2/access.log

Thank you: this is the ouput of the counters:

kmemsize has a lot of errors. Does this mean the server has to less memory?

You might want to try to configure your apache to start less instances and set the max number of instances to a lowe limit in apache configuration.

Ok, thank you, but can you help me with this? I don't know where to find these settings
