Re: [jgroups-users] JGroups failing to give up on crashed coordinator

Now that I have removed flush I occasionally get state transfer failures on
the initial connection to the cluster because I'm getting a timeout from
BARRIER.

Would those OOB threads be for incoming or outgoing messages?  I get the
view callback prior to this error which may cause me to start sending some
messages out.  On other nodes the view change will cause them to send
messages to the new node right way.

If I don't figure out what is causing this / how to avoid it soon I will be
forced to put FLUSH back in.
