Server Crashed when map changes!

I have an RP Server, and when switching to some maps the server will shutdown, with the normal shutdown message:
“Disconnect: Server is shutting Down”.
I contacted server host and they said: It is either a corrupt addon or something
Any solutions?

use changelevel instead of map

map restarts the server
changelevel changes the level

I use the ULX map change, and even with changelevel, it does still crash.
Any solutions?
