Problem A critical server error occured handling a packet

My server keeps getting random restarts and I get a Severe server error. I'm not sure what to do to fix it and was looking for any input. The server permgen is set to 512. FTB Unleashed 1.1.7

Inventory size mismatch between client side and server side on some container when someone is trying to sort with inventory tweaks.

You can remove inventory tweaks on the server and it will stop that error, but sorting will not work as well.

I'll try removing inventory tweaks to see if the server stops crashing.
