Not sure what is going on. We made sure that the port (388) is open (cleared the firewall). Apparently the data were sporadically flowing when our ldm was using an unretricted port # - now nothing is flowing! The upstream provider notes that their ldmd.log file shows steady RPC unable to receive messages, and starting up messages that are logged before the error and exit messages from the last connection.

This sounds like their iptables or firewall is turned on at full blast.
And if they just did an OS upgrade, there's a good chance, by default, the firewall is turned on and blocks everything except mail (when I installed Fedora Linux 7, that was certainly the case). A firewall problem may have gotten you some data before, but the new LDM and OS probably don't tolerate that.
