I'm also getting a lot of Chunk Pointer errors which I can somewhat fix with "Chunkster".

My current plugins are:
BigBrother
Worldedit
Worldguard
Essentials
EssentialsChat
EssentialsSpawn
LWC
LightVote
mcbans
Permissions
SimpleHome

What can I do to get these from coming back? It will scroll these and chunk pointer errors indefinitely. Also, it happened right after my computer completely crashed.
