Open 1.4.1: [1.5.1]Server crash with no crash log

[hikyuuri]

Version:
1.4.1

What is the bug:
Since updating to 1.5.1 earlier today, my server has crashed randomly and rebooted with absolutely no crash report or any hint as to why it crashed.

All I have is the McMyAdmin log showing the console saying the following:

Console : [18:49:26] [Server thread/WARN] [FML]: Unable to lookup chisel:cobblestoneWall for public static com.cricketcraft.chisel.block.BlockMarbleWall com.cricketcraft.chisel.init.ChiselBlocks.cobblestoneWall. Is there something wrong with the registry?

Notice : Minecraft server has stopped running.
Warning : Server stopped unexpectedly! Automatically restarting...

I have no idea what is going on here, and I do believe this is independent of my other issue with headcrumbs.

I have reverted back to 1.4.1, and the server crash issue went away. Headcrumbs is still broken though.

Can it be repeated:
It REALLY did not like me in the Twilight.

It would crash about once every 30 minutes or so, but when I went into the twilight, it would INSTANTLY crash every time I reconnected. Other people could connect in the overworld without issue, but every time I connected, instant crash.

Known Fix:
Revert back to 1.4.1

Just an update,

The last time it did it, everyone on the server made mention how it seemed like time jumped back a couple minutes. What I mean by that is, things that people created were gone, but only for the past couple minutes.

It was not server lag as we were still interacting with everything (ME System, for example). I myself noticed it too, I had crafted and placed an extra 20 wireless extenders in a wireless access point before the crash, after the crash I was still waiting for the pure certus quartz to finish processing.

This lead me to think it was a drive space issue, but checking the drives shows that they are not even 25% full (one drive for Minecraft, another for a DynMap).

Anyone have any ideas?
