This is not a bug.

The server is telling you exactly what is wrong.

Caused by: net.minecraft.util.SessionLock$ExceptionWorldConflict: /root/Minecraft/./world_nether/session.lock: already locked (possibly by other Minecraft instance?)

Your nether world is locked by another instance. This means you're running two versions of the game on the same world, or the last instance ended before it could unlock the world(s).

If you can verify for certain this is the only instance of the server running then you can manually delete the file lock(s) mentioned in the log.
