    My server had been running very smoothly and suddenly crashed. Now, whenever anyone logs in it freezes then crashes again. I'd really appreciate any help

    Try updating your Java.
    It could be a corrupted player file/chunk. You could try resetting the player .dat files, but this will clear inventories and reset the players to the spawn point.

    It ended up being a BuildCraft bug with the filler. I have no idea what caused it, but that chunk the filler was in was the culprit. I had to rollback the server a few hours which, of course, always makes everyone very happy.

    It's better than needing to wipe the map!

    What are you using for rollbacks if I may ask?

    I'm using the saved worlds from the ClanForge console.
