My server has an error/crash bug. It appears to affect a particular part of the world. It took me a while to figure this out as the anomaly/glitch/whatever was in the spawn chunks. Moving the spawn point several hundred meters away fixed the problem EXCEPT when the glitched area is loaded.

Futhermore, I have tracked the location and last known direction of movement of player entities when crashes occur and charted them. From this data, it looks like this crash happens when the affected chunk or chunks load(s) or unload(s). I believe this to be a sort of world file, chunk, or block corruption.

I currently have no other information about the nature or cause of this corruption.

This issue began affecting the server immediately after updating to release 1.8

There are two distinctly different errors in the enclosed crash logs, and they appear to alternate.
