1. Re: Slow failover
mohitanchlia Dec 29, 2008 10:05 PM (in response to mohitanchlia)Could it have something to do with TCP sockets? I even tried to reset max tries in FD to 1 but it didn't help. We are using default out of box cluster-service.xml file.

2. Re: Slow failover
mohitanchlia Dec 30, 2008 4:23 PM (in response to mohitanchlia)I did more analysis and it looks like after back end nodes detects one of the node is down it re-elects the master (after calling ElectionPolicy), after that jboss just pauses, it just halts. Could there be a bug with how Proxy stub at Front end box is not able to make the remote call and just hangs?
I am just wondering why would rebooting one box cause all other boxes to hang and why would EJB call not round robin in this case. -
3. Re: Slow failover - Plz read
mohitanchlia Dec 31, 2008 5:16 PM (in response to mohitanchlia)I got the logs and it shows me that Jboss is continuously trying to connect to the host that just got rebooted or crashed. I thought when EJB is @clustered it will round robin the invocation and not try same host over and over again. But what I am seeing is that Jboss repeatedly tries to connecto failed host. Could someone tell me what's going on?
