Problem Server Infinity 1.10.1 Crash : ConcurrentModificationException

[Iguane]

Hello everyone !

I'm running an Infinity Server for a month and since last night two server crashes occured. I'm running 1.10.1 version and my server is hosted on Linux.

This is an extract of the crash log (the full file is attached). Anyone could help me ?

Thanks

What happens when you disable fastcraft on the server and restart?
