Tekkitlite Server crashing for unknown reasons [Need Help]

[Phreag]

Hey guys

 

My Tekkitlite server crashes sometimes for unknown reasons.

It doesnt create a crash report file, but from the server.log i got this report: http://pastebin.com/jDXfrmaw

 

We already did those steps:

 

- We detected that the crash came from loading a specific chunk. then we restored the chunk from a backup.

 after some times the server crashed again. Deleting the chunk file helped, but now all the buildings there are lost.

 

- We got this problem some times in the past with the same effects. Sometimes restore from a backup fixed it, sometimes not.

 

Does anyone know which specific action done by a user can cause this?

Thanks
