    Description

      Description


      So it appears that the issue is that Minecraft can take a long time (minutes some times) to notice that a player has disconnected, and if the player reconnects before that happens, bad things happen:
      1) Minecraft will now never notice that the original connection failed, spam the log with the "forcibly closed" message, and hang at shutdown.
      2) The player will now be in the server twice.
      3) [redacted] badness derived from problem 2.
      This definitely never happens in 1.7, and has only recently started (for me) in the 1.8 snapshots.
      This is not a duplicate of MC-38565 it is a duplicate of several other bugs that have been closed as duplicates of MC-38565 but that's what happens if you dismiss valid bug reports as duplicates.

      This basically sums up what happens, but to add to this it appears that at random times the server just decides to not update the player list
