Server random startup freeze/crash

[Chas]

For some reason my server freezes randomly at startup (note: doesn't always freeze, only 30% of the time)

after it writes, the screen freezes (have to detach/kill process)

According to my research, it's a problem inside the server.cfg file....
So the question is, what command is making it freeze from the server.cfg?
