The problem with the hang when booting the all configuration
seems to be gone now, but I'm still seeing the clustering
take a long time to bootstrap.
It always seems to be stuck here:

Is your server bound to your VPN interface?
GMS: address is 10.11.14.31:32796
This sounds very similar to what the dev90 machine was experiencing when
doing hudson testsuite runs. There, multicast wasn't working properly
on the bound interface. FLUSH counts on getting back a response to its
own multicast, which it would never get. So, every startFlush would
hang for timeout * retries.
This gives me a chance to bring up something with the JGroups guys:
The behavior we see when FLUSH fails seems not so great -- long delay
and then a WARN. At least in some cases, like initial channel
connection, it would be better if it the connect() just failed. The
channel is not usable.

Noted Brian. We over engineered FLUSH in 2.5 release and in 2.6 release
which is due next week these kind of issues should not happen.
I'll try AS-HEAD with JGroups HEAD before ship it as 2.6.

Try setting multicast path through localhost or a multicast capable

or
ip route add 224.0.0.0/4 dev lo

Note that IP multicasting does *NOT* work over the VPN ! Even worse: on
my box, IP multicasting does *NOT* work over the interface which is used
by the VPN. Event if the VPN is NOT running !!
You have to de-install the VPN crap software to get this to work...
Cisco knows about this.

Yeah, it's not. If you don't specify -b or otherwise specify how
JGroups binds, JGroups picks the first non-loopback interface.
The only issue here is how much we care about whether we can still say
"go to two nodes and './run.sh -c all' and you'll have a cluster".
TBH,
I don't much care about that any more and have no objections to having
the AS set a localhost default. Would be interested in opinions of
others though.
(BTW, clustering JBM requires assigning a unique server peer id to each
node, so "go to two nodes and './run.sh -c all' and you'll have a
cluster" doesn't work anymore anyway. JBM guys might find a solution to
that though.)

Yes, that should be changed. The code in this regard should resemble that main() in
Branch_4_2.

You mean deep copy 'all' to all2 then:
run -c all -b x.y.z.1
run -c all2 -b x.y.z.2
That should work, like it does in AS 4.2, yes.
One glitch, is the "Post Office" of the new messaging. It prints out a
warning/stacktrace
when the 2nd instance in the cluster boots. I think that should work out of the box
without
problems.

New subject: Not binding to localhost by default in jboss-head was: Re: Clustering bootstrap still taking a long time
I've fixed this in head.
http://jira.jboss.com/jira/browse/JBAS-4954
But I think the code in jboss-4.2 for the defaults for other
bind address is wrong.
It currently says:
// JBAS-4119, set the java.rmi.server.hostname if not set
if (System.getProperty("java.rmi.server.hostname") == null)
{
System.setProperty("java.rmi.server.hostname", "127.0.0.1");
}
This has two problems:
1) It doesn't set the other bind addresses
2) It doesn't necessarily agree with what the real bind address is.
In fact, it doesn't resolve the problem I'm seeing because
it doesn't set the jgroups.bind.addr property.
In jboss-head I've made the code:
// Fix up other bind addresses
String bindAddress =
System.getProperty(ServerConfig.SERVER_BIND_ADDRESS);
if (System.getProperty("java.rmi.server.hostname") == null)
System.setProperty("java.rmi.server.hostname", bindAddress);
if (System.getProperty("bind.address") == null)
System.setProperty("bind.address", bindAddress);
if (System.getProperty("jgroups.bind_addr") == null)
System.setProperty("jgroups.bind_addr", bindAddress);
Dimitris, is there a reason why you didn't fixup all
the bind addresses (see the -b handling code) in 4.2?

That's a deprecated property replaced by jgroups.bind_addr; the only
