Note that the distros are still including the old incubator

Should we have release notes for this release somewhere? NEWS.txt doesn't have 
an 0.6.2 section.

It's been removed in SVN; it won't be in the next release.

Thanks ant!

It looks like we've evolved into a pattern of documenting major
releases in NEWS.txt and bug-fixes in CHANGES.txt.

News might be a misnomer here, that file is for release notes, (i.e.
things you should be aware of when upgrading, new features, etc).
Considering the scope of changes for point releases, there shouldn't
ever be any entries between major stable releases.

Do you have a specific example of something that you think was omitted?

GMFD messages

[Anthony Molinaro]

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

Hi,

  Still haven't heard from anyone about this, while the restart helped
temporarily, it now seems to be broken again.  I restarted one node
with TRACE logging on, and I see this

INFO [GMFD:1] 2010-05-26 23:44:44,260 GossipDigestSynMessage.java (line 129)
   Breaking out to respect the MTU size in EPS. Estimate is 56 
TRACE [GMFD:1] 2010-05-26 23:44:44,260 Gossiper.java (line 293)  Size of
  GossipDigestAckMessage is 1374
TRACE [GMFD:1] 2010-05-26 23:44:44,261 Gossiper.java (line 937) Sending a
  GossipDigestAckMessage to /10.192.63.127

So it seems like cassandra needs 56 bytes for each server in a gossip packet
which with a maximum packet size of 1428 means at most you can have 24 servers?

Which sort of sucks, since I have 27 right now.  However, I'm not certain
how this would explain what I see which is a complete cluster restart works
fine for about 14 hours, then suddenly no longer works?

Ideas?

-Anthony
