Classification: UNCLASSIFIED Caveats: NONE I have also had issues with this in the past. I know that this was a problem in 1.6.3, supposedly fixed in 1.7.4. For some reason, when attempting to set up inter process communication this way you are only able to connect once.
I still have issues as of 1.8.3, but as the actual error is of the form: ------------------------------------------------------------ A process or daemon was unable to complete a TCP connection to another process: Local host: xxxxxxxxx Remote host: xxxxxxxxx This is usually caused by a firewall on the remote host. Please check that any firewall (e.g., iptables) has been disabled and try again. ------------------------------------------------------------ [xxxxxxxxx:59057] [[9837,0],0]-[[9830,0],0] mca_oob_tcp_peer_recv_handler: invalid socket state(6) I suspect it may be a local configuration issue as opposed to an issue with the code itself.
