What OS you use?
How do you start JBoss and did you change the configuration?
I'm using Linux. I start it through a shell script. I have a custom profile that is based on production profile. It was working fine as I had mentioned already. But yesterday I tried to start 2 instances. That's when the problem happened. The port bindings were all set properly though. Is it beause of the hostname of the machine?
How do you start the two instances?
Do you use the same directory and start with run.sh both instances?
Please provide the shell comand line.
