Problem Server crash last night, now wont start :(

[Deor]

Hi there,
Have been running FTB on my linux server for a few weeks now without a problem. Last night at some point it crashed and now wont restart. Would apriciate it if someone could give me some advice on fixing this is possible.

This is a Debian server running in an OpenVZ virtual machine with 2gb of ram.

In reading the log the first thing i see is "IC2 Pump" and "Moving object"
was someone trying to pickup a pump with the portal gun?

Unless someone comes up with a better idea,
backup server
load in world edit
remove entity’s

Thanks GP, that is indeed what i did to fix the problem. Luckily there was only one person playing with pumps so he knew where they were. Opened the map in MCEdit and deleted them and it worked fine after that. There were a few problems with some machines breaking and wire turning into pumpkins in the chunk that was edited, but we fixed that up and all is ok now.

Dont think this was portal gun related tho as im the only person who has one and i was asleep. So far so good with the new pump setup!

How do i set this as 'Solved' now?
