Paul,

The first place to look would be in the LDM log files of both the upstream and
downstream sites.
If a notifyme(1) command executed by the LDM user on the downstream site to the
upstream site indicates that the downstream can receive data, then the LDM
system on the downstream site should receive the data. It would then be
unlikely that any problems with data reception are due to the LDM system.
Perhaps the bandwidth of the connection is insufficient. A large latency would
indicate this. You could put the downstream LDM in "verbose" logging mode
(ldmadmin start -v) and look at its log file to see what the latency is by
comparing the creation-time of each product with the timestamp of the log
message.
