Hi everybody

Our websever, Linux Debian with mysql, apache2, php 5
went down this saturday. Now this monday morning i must find out why this happend. I am loooking for the the correct log files. We know that the server was available by using ping so it is (was) an application failure. We know that the our apache support team had changed the php to improve performance to apc.shm_size=192M (a couple a weeks ago) because couple a weeks ago we got a "Unable to allocate memory for pool" error message. Our server is running on a Vmware Server version 3 as virtual machine with sufficiente CPU and RAM resources. Where and which log files must be checked to avoid future downtimes please help - thx in advance

It should be in /var/log/apache2/error.log on your system (debian).

Hi,

/var/log is probably a good place to start looking for errors/warnings etc. I would first focus on the Apache logs, but also have a look at the other log files (you seem to assume that Apache is the problem, which could be true but might not be true).

If the apache log files are not in /var/log ask your Apache support team where the logs can be found.

Hope this helps.
