jboss ha weirdness

I don’t know enough about jboss to make an intelligent keyword filled post about this, but I wanted to note that while troubleshooting jboss ha-jndi jms crap, make sure that telneting to port 1099 produces an fqdn. on a couple servers /etc/hosts had a different hostname portion of the fqdn than the hostname alias, and this silently broke JMS. Telneting to 1099 revealed this, or at least, indicated it was dns related as working boxes were giving an fqdn while non working boxes weren’t. I think jgroups isn’t friendly with dns over all.
