Server Shutdown and/or Crash

How is this resolved when it still crashes on 14w25b and how is this a duplicate of MC-56893? MC-56893 happens when you place a log block and the crash/server shutdown I reported happens every 2-3 minutes without building or placing any block. Also there is no crash report the server just shuts down. Here is the server log from 14w25b.

I can confirm this, this is really annoying and different from the log crash. This causes hosted servers to close and restart because of an apparent error.

Can also confirm this for 14w25b, server seemed to crash on a player joining. Have been running this server snapshot .jar since last Friday, and this is the first time I have encountered this issue. Included a log extract below, though I have removed the players name, UUID & IP. Upon the crash, no crash report was generated & the server appeared to have been stopped as normal.

Same issue here. It doesn't generate a crash log. And it only started doing this after about a week on the new snapshot.

I have many crash reports which now make no senese to me tat all to whats going on or whats causing it.

Still no fix?

This issue is still occurring

I know still does it in pre 1.8

Is this still an issue in the current Minecraft Snapshot 15w47c or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Ticket resolved as incomplete, because no answer in a reasonable amount of time (1+ year), if it still happens, please update the ticket.
