Hi,

  I noticed yesterday I have lots of these messages

INFO [GMFD:1] 2010-05-25 23:21:04,070 GossipDigestSynMessage.java (line 152)
  Remaining bytes zero. Stopping deserialization in EndPointState.
INFO [GMFD:1] 2010-05-25 23:21:05,224 GossipDigestSynMessage.java (line 129)
  @@@@ Breaking out to respect the MTU size in EPS. Estimate is 56 @@@@

The first message only occurs on some machines in my cluster.  The second
on all of them.

The ones with the first message seem to be building up quite a backlog
in their MessageDeserializer PendingTasks.

I assume there is a correlation, what could be causing this sort of thing?

This cluster is now at 27 m1.xlarge boxes on ec2 running 0.6.2 of some flavor.

I ended up restarting one of the boxes which was behind and when it came
back it only had some parts of the ring, so I shutdown everything, brought
the seed nodes back, then brought the rest back and that seemed to fix
things, but this definitely seems like some sort of bug with gossip?

Thanks,

-Anthony
