Many FTB and other servers are having this issue which is causing crashes frequently and varies depending on the server, in our case we have been having hourly crashes, so we have had no option but to put a temporary server online until we can find a resolution.
This is not related to TickThreading, the mod. Many servers with and without the mod are having the issue.

Thanks for taking al look!
 
Has anyone resolved this issue? Our server is suffering from these crashes as well running latest MindCrack on MCPC+.
Not sure if it's related to MCPC+ or not.

Crash report

Also, one of my players reported a chunk reverted back to wilderness, this chunk was on the first home she made with all her storage items gone. I had to revert to a backup. I will investigate what mods is being use in this chunk that may have caused it. This isn't related to this thread.
 
As far as I am aware, this is only MCPC, its due to the way it handles chunks, it interferes with how FTB Handles chunks.
