2.3.1 on Slackware 10.2 (current) 2.4.32 kernel
I updated a working 2.3 server to 2.3.1 by overwriting /opt/jive_messenger
Now nmap shows that the server is only listening on 9090, not to 9091 or 5222 & 5223
The admin server is working
The Linux distro does not have a firewall enabled
Nothing odd showing in jive_messenger/logs or /var/logs
