The Server crashed when I tried to run this HUGE map rotation. I put in a support ticket and waited. They asked me if the server ran with a smaller rotation and I changed it back to just "dm" and it did work. I asked them to tell me why this was so. Here's how they replied from Gameservers.com
Dear Customer,
Ticket WGL-87936 has been updated by Beau Young [staff].
I could not find official info on it, but I did find an unofficial source recommending to keep the number of maps in the maplist at 34 or less. It may be a limitation of the game. To confirm or bust this statement, you can try adjusting your map rotation to 34 maps. If the server works, add one more map to the rotation at a time until the server stops coming up on a restart.
While it took them several hours to get back to me when the server was down, I am truely impressed that they stuck with this issue and gave us a solution. (Compare that to FPS gameservers in the DOD forum Support Tickets). I recommend we re-host with these guys.
