Hey I am also the sort that is quick to anger sometimes. But as an admin I think you should try to be as tolerant as you can of your players for the sake of professionalism.
I freeze a lot at random times. I haven't noticed any pattern. Just once every few hours on average, the game freezes as though I'm lagging out, and I have to close/reopen to regain control. It's not a client crash. As I said it happens to some friends of mine as well, but the frequency seems to be different for different people. I don't know what could be causing it.
