Odd. Any idea if it still > occurs with a more recently built kernel? I've felt like I tried everything so far, and I cannot figure out what the problem is, I've done numerous hardware tests, and every single one was passed with flying colours. I have narrowed it down to apache locking the box though. So I'm not sure what I can do to fix this, because it is very tedious to have to keep manually rebooting the box everytime it locks (sometimes 3 times a day!) Can anyone please suggest something to fix this issue? If any of the developers read this, I can give you ssh to the box if required so you can see what's happening.
