GMod Server Crashing and Errors

Hello Facepunch, I run a TTT server with ULX, and whenever we kick people it crashes the server, and this is a constant error:

 date control point 0 for effect 'blood_impact_synth_01_arc_parents'.

it keeps popping up and there is errors like this one too and its causing problems with the server.

Lately there have been problems with the server crashing frequently and randomly, the logs of the server and web console when it happens show nothing out of the ordinary. Also people have been timing out and their steam auth tickets being cancelled for no reason. We have used the server hosting service for months now and never have experienced something like this. I will reinstall ULX the next time it crashes due to the kicking problem, but any idea what the other problem is?
