maps crash when changed please help

[ComputerHelper]

i have a surf server set up (16 slot 66tick 512fps fast dl) and every time the map changes, it goes way to fast, okay so heres where the problem starts, when people join a team the server crashes and then restarts. i think it might be the fast dl even though i have 2 other servers up and the fast dl works fine so im just lost

Could it be a bad map?
What mods are running on the server?
