Apache causing server overload
For the past year our phpBB2 based Forum has run perfectly well on a dedicated server. The phpBB2 version is 2.0.10 (newest). Lately we have experienced strange behaviour. Some Apache processes take all the CPU capacity and even more from time to time and cause the board to become unaccessible. I suspect there is some looping processes that take more and more resources and newer end.
Is there a way to track these processes in order to verify that they are caused by the phpBB2? By using the "top" command from the shell I can find the jamming precesses' PID. I would really like to know what page is being handled by the PID in question.
We have tried to limit the process run time by editing the php.ini and httpd.conf files, but these processes seem to run despite that.
The "top" command displays that normally only a fraction of the resources available is being used, but as soon as the evil processes start, everything is exhausted.
Best Regards,
