Server Repeatedly Crashing, generation related?

Hi, our multicraft server has been running smoothly up until just now when it started crashing repeatedly. At first it was happening every minutes or so with the error state engine in SERVER STOPPING. Now it seems ok, but when i try to generate new chunks the server seems to crash. Here is my crash report

--Edited out--

UPDATE: after changing one of our mod config files, we have now returned to the state engine having issues. here is the new crash report.

Any help is much appreciated! Thanks

 

pastebin the startup log from a fresh start, and or the java errors on the server log during a crash.

 

Here you go, never used pastebin before so i hope it works.

Definitely appears to be caused by whichever mod contains this method:
com.globbypotato.rockhounding.handlers.StructureGenerator.generateSurface

The system is choking on bad data, corrupted data, and unable to turn the world map files ito a proper world. Removing that mod should hopefully fix the problem, unless the map data has been corrupted badly enough that it is still unreadable(usable) without the mod present. In which case, a run through RegionFixer to fix your corrupt map (which may be be a small amout or huge amount of missing data when you do recover) is worth a try {you will need to find that resource and istructions, it is very involved to setup and use.
