Server Crash [SECUREGMOD]

Hi! Since a few hours my server only crashes when a player enters the server and the last line I can find in my console is"[SECUREGMOD]: Preventing JIT from being disabled"

Where the problem can come from and how to avoid it... I pay all my addons on gmodstore, and I don't have to my knowledge change a few things his last hours...

My server is hosted on Mtxserv.fr.

Thank you in advance!
