HI Filip,
can you explain your 6.0.x fix ((http://issues.apache.org/bugzilla/
show_bug.cgi?id=40042).) a little bit, please?
I think we hava only a chance to recover membership after cluster
membership send failure, to reopen the socket.
Here my current cluster 5.5 fix:
==
public class SenderThread extends Thread {
long time;
McastServiceImpl service ;
public SenderThread(long time, McastServiceImpl service) {
this.time = time;
this.service = service ;
setName("Cluster-MembershipSender");
}
public void run() {
long retry = 0 ;
while ( doRun ) {
try {
send();
retry = 0;
} catch ( Exception x ) {
// FIXME: Only increment as network is really
down: NoRouteToHostException or BindException
retry++ ;
log.warn("Unable to send mcast message.",x);
}
if(retry > 0) {
if(retry * time < timeToExpiration ) {
try {
Thread.sleep(time);
} catch ( Exception ignore ) {}
restartHeartbeat(retry);
} else {
long recover = retry % 10 ;
try {
Thread.sleep((recover+1)*time);
} catch ( Exception ignore ) {}
if( recover == 0) {
restartHeartbeat(retry) ;
}
}
}
}
}
private void restartHeartbeat(long retry) {
try {
socket.leaveGroup(address);
} catch (IOException ignore) {}
try {
log.warn("Restarting membership heartbeat after send
failure (number of recovery " + retry + ")");
service.setupSocket();
socket.joinGroup(address);
} catch (IOException ignore) {}
}
}//class SenderThread

I'm sorry, I just reread friday. Friday next week is totally fine.
No one should have to work on a weekend.
also, for the mcast problem, I'm implementing a fix in 6.0 and 6.x,
you should be able to copy that one
Filip
I think that will suffice.
Regards,
Rainer
