TTT Server crashing on mapchange and randomly


my TTT server keeps crashing very often and i dont know why.
There are no errors in the console.
It just restarts.
I asked my hoster very often about that and they could not tell why it is crashing.
I only know that the workshop addons are not the cause.
Can you help me please?

It seems ULX is causing these problems.
Should i use a older version of it?
