      [20:02] <roxspring> grrr - just noticed that the hudson has put the slaves offline
      [20:02] <roxspring> am getting this sort of thing an awful lot lately
      [20:07] <roxspring> typical slave logs go like this: (see below)
      [20:08] <roxspring> then the slave services won't start up "Error 1067: The process terminated unexpectedly"
      [20:09] <roxspring> seemingly another rejected connection
      [20:11] <@kohsuke> I know this issue
      [20:11] <@kohsuke> It's because Hudson thinks the slave is still connected even though it's not any more
      [20:11] <@kohsuke> We need to fix this
      [20:11] <@kohsuke> roxspring: if you can file a ticket, that would be great.
