[SERVER] CLIENT Randomly crashes! I Need help !

Hey Guys!

I really dont know what i can do, also i dont know how to find it. I cant remove all addons. Its an Public Server and is mostly full, also the error is randomly i cant say if it helps only when i test it every time for 2 or 3 days and hope.
