Server crash on map change

[Demo]

So, I was learning for exams and my team from TTT and RP spammed me with "The server crashes on map change" and its true.
This problem came out of nowhere. I have not changed a single thing. Then I removed every addon one by one and found out that ulx /ulib is causing this error:

Code: [Select]

Ammo crate detonation con var created
Segmentation fault (core dumped)
Add "-debug" to the ./srcds_run command line to generate a debug.log to help with solving this problem
Fr 22. Jun 16:29:11 CEST 2018: Server restart in 10 seconds

No map works except the start map. Not ttt_ map or rp_ map. Any idea? It worked perfectly some days ago...

[Demo]

This effected all my servers at the same time: 4 TTT servers, 1 DarkRP, 2 Testservers and 1 MilitaryRP server. No map can be changed and it's only because of ulx / ulib.

I'm wondering I am the only person getting this issue

Edit: Found out, ulib is causing this issue. But still searching a way to fix
