Web server time out - How to trouble shoot.
I'm using my linux box, with Red Hat, to host my personal website and email. While logging into the web mail through out the day, I've noticed that it's "locking up", becoming unresponsive and timing out. It doesnt' display web pages while in this state. Later, it will be fine.
It's something that's started over the last month, after working flawlessly for a year and half.
I cannot check it now, I'll have to diagnose the problem when I get home.
What logs or tools would you suggest I run or read, to help me find what's causing it to time out?
How do I find out what's causing it to be busy? Am I being hacked? Is there a cache or log file I need to empty?
