Did yoiu try to edit a config whilst server was running, if so did you ht the reload button?

 

I do that all the time, but in this instance, no. I just happen to be watching the console and it happened. attempted to login and couldnt, so i just restarted. Never seen that message before.

 

Do you have NoCheat? It seems to happen with NoCheat more often than any other plugin.

 

Ya, I saw someone post in the performance tweaks plugin that they get the same crash, so it may be related to that.

 

I have had problems like this with 'Optimine', deleting the configuration files solved the problem.
