Problem Infinity server crashing

[Trollulz]

So I woke up to seeing the server having crashed around 5 - 6 times, I suspect that a possible corrupted chunk is what's causing this. But honestly reading the crash logs, I find them a bit confusing, server logs I'm fine with though, however there doesn't seem to be anything relevant in the server log, other than it just randomly starting to shut down.

Infinity server 1.2.1. - 1.7.10
Using Cauldron.
Disabled mods are fastcraft and Not Enough Resources

Here's the server log from one of the crashes:

Two of the crash logs:

It has been quite a few hours since the last crash now though, but I still would like to look into what's causing it.

load a plugin called SetBlock

Then log into the game and use the command /setblock 0 -481 64 -2246

there is a block causing problems in that location. the command changes it to Air
