Server crashed, wont load World again.

[PyroxHu]

Hello fellow Players,

Me and a couple of friends rented a dedicated server, and we had a pretty good time playing but with a couple of server crashes.

This is the last log entry before the crashes:

eac_server.so [x64] :: OnLoad()
mono_fdhandle_insert: duplicate File fd 0
Receiving unhandled NULL exception
#0  0x007fe995d7d42a in abort

Its a linux based server (4,5gigs of ram approximately, with a maximum of 6 players.)

Usually the server did start right after the crash, but this time it did not start at all.

I deleted some names from the log because of privacy.

This is the log entry every time i try to start it. In my opinion the World files are somehow corrupted because of the crash. I tried to reinstall the server but no luck.

Is there any chance that we can play this World again?

First make a backup of your save game. ( /home/users/***/***/game/7d2d_26905/.local/share/7DaysToDie/Saves/Hizoni Mountains)

Delete all your region files (the files in /home/users/***/***/game/7d2d_26905/.local/share/7DaysToDie/Saves/Hizoni Mountains/kotorek/Region) . If you can start the game, it really is a corrupted region file and you can do the following:

Copy back the region files from the backup (copy, not move!!)

Now delete half the region files. Test if the game starts. If yes, the corrupted file is in the deleted part, if not it is in the part you left undeleted.

Restore/Keep the region files with the corrupted file and again delete half of them. Test again to see in which half the corrupted file is

Do this so called binary search until you know which region file is corrupted (hopefully it is only one).

Restore from backup again and only delete the corrupted file. Your world should be back except for one region that will be reset. If you are unlucky this could be the region with your base in it though

If it is a player file that is corrupted you could also try this:

Long-term tip: Backup often (you only need to backup the save game, anything else is static stuff or can be regenerated as long as you use the same serverconfig.xml).
