The gameserver always shutdowns after the 3rd map, and it doesnt matter what map it is - i changed very often and tested. To test i changed the time from 30min down to 1min (time based game).
All maps are installed and available with proper rights - double checked. I also deactivated for testing the iptables rules listening on length (Fu's rules), but no effect.
I confirm this bug. I had already noticed some crashes on restart (either single or multiple maps). You're right, it seems to happen on 3d restart. To be honest I didn't remember this bug - a rather annoying one. I also newly compiled the late svn1341 on Linux and the bug is there too.
