The log file for the LDM on Noaapxcd contains many entries like this:

> Jan 12 07:46:06 noaapxcd noaapnew.it-protect.com[12830] ERROR: readtcp(): 
> select() timeout on socket 4 

This indicates that the downstream LDM on Noaapxcd was unable to obtain a 
complete message from the LDM on Noaapnew within 30 seconds -- indicating a 
problem with either the LDM on Noaapnew, or Noaapnew, or the network between 
them.

The log file also contains entries like this:

> Jan 12 16:12:53 noaapxcd noaapnew.it-protect.com[12830] ERROR: Disconnecting 
> due to LDM failure; Couldn't connect to LDM on noaapnew.it-protect.com using 
> either port 388 or portmapper; : RPC: Program not registered 

This indicates that the LDM on Noaapxcd was unable to contact the LDM on 
Noaapnew using the LDM's well-known port number of 388 (a serious problem) and 
that the LDM on Noaapnew wasn't registered with the Portmapper on Noaapnew (a 
not-so-serious problem *if* the LDM on Noaapnew is listening on port 388).

Does the log-file for the LDM on Noaapnew have anything to say?

Offhand, I'd say that there's a problem with the network between the two 
systems. What does a traceroute(1) show?
