Funny you should mention high session time outs.

I was given a task by a friend to look at, on something that I did many
years ago. Since then they had another developer come in make some changes
and the server fell over about 5 times a day, when I looked at it, the
session was set to 2 days, I was like WTF...

Change it back to what I had set it at 6 years ago, and 8 months later it
hasn't fallen over once.
