Random server crashing: Exception ticking world

[cc4_4h16a]

I have recently start a server with my friends on forge minecraft 1.9.4 with 36 mods installed. However, the server often randomly crashing, with Exception ticking world, yet I could not figure out what is the problem. The server first crash is when I use the Angel Ring from Extrautil2 to fly around and explore the world, it seems that whenever I flew too far that the chunk containing the GP generators unload, the server will crash. However, recently the server just randomly crash even if I am inside that chunk. Could anyone help?

 

Here is the crash report:

I have removed and checked all the mods, it seems that it is EnderIO causing the problem. Upon further testing, it should be some EnderIO blocks in game causing abnormal chunk loading and unloading, anyone has any idea what it would be?
