I'm still using r8886, so I haven't tested this with the new version, but...
I setup a dedicated server on a friend's linux box (Centos 6.2), and everything seemed to work. It was even nice not having to deal with saving the game, we could just leave it running and come back to it anytime...
Until today. I got an IM from my friend saying the MM was "Chewing up a good chunk of the cpu" which is really odd because it wasn't doing anything, just sitting there waiting for players to show up to do the next turn. Resetting the server didn't really fix the cpu usage, so I simply killed the server.
Is this normal for a MM server? Was it a function of how long the server had been up (a little over a week)? Something else?
