Wow, it looks like you set all the cvars to server info cvars. That makes the server send out all that information whenever somebody requests server info. Packet sizes are limited, though, so data starts getting cut off if you try to send out too much. Those warnings shouldn't really just be ignored.
I'm not sure if that was directly related to the crash or not - might have been overflowing a buffer. As for debugging, if you're running a linux server, you can use gdb:
gdb paintball2
run +exec whatever +map yadda yadda
