Problem crash server

Hello, I have been using SafariNet for a while, I have no complaint about its functionality since it carries out its task fully.

I have had to remove it from my server for now since a few days ago there are users entering with hacks like "SpeedNuke" and they have managed to shutting down my server on several occasions, I have tried all the other plugins and when uninstalling this in particular we haven't able to reproduce.

I don't know what kind of costly actions it performs, I attach the crash log.

Regards
