Hello,
I am using the Crundeecraft modpack, but I had it before this whole problem emerged, so it's probably not the modpack itself. I do have to note that since some time Not Enough Items got disabled, however I can still join my server.
My server keeps crashing because of an "ticking entity" this happens at random moments and it is not an issue when starting or when a player joins. It keeps happening more and more (prior it was each hour, now it's each five minutes, which is really irritating considering the fact it takes 10 - 40 minutes to start the server.)
Here is the log about the crash:

Here is the full log of the latest crash:
I would think this would stop if I created a new world, but that would erase all my nice survival buildings 
If anyone could help me out that would be awesome!
