Hi Igor, I use awstats, but that also doesn't show too much (I looked at the actual logs of apache in the period when this problem happened). I also think it's either PHP or MySQL, but there are very many scripts on the server, first I'd like to know which script/file is causing this, then I can look at the script and see what could be causing this. I've created a small script that checks the loadavg every minute and if it's above 3 it logs output of ftss into a file. Now I just have to wait for the problem to occur again.

Without the config file we can't say what else might be wrong, it might be KeepAlive and/or Timeout settings or something similar ... |
