The Linux system is getting the CONDUIT data from Bigbird and relaying it to 
the Solaris 5.10 system?

We've seen firewalls do some strange things.  I don't recall this particular 
behavior, however.  Usually, a firewall prevents a connection from being 
established at all.  Firewalls are, however, general-purpose computers -- so 
they can do almost anything.  Some firewalls have packet-shaping capabilities 
which interfere with the LDM (they artificially limit the amount of traffic).

Do you have a network administrator who could vet the configuration of your 
firewall?
