Mike,

First off (and this needs to be fixed before we can continue) the following 
entry in /etc/hosts on Derecho

127.0.0.1               derecho.sonomatech.com derecho localhost.localdomain 
localhost

should be changed to

127.0.0.1               localhost.localdomain localhost

and then Derecho should be rebooted after the LDM is properly stopped.

Our initial impression is that the full bandwidth of the 500 kbps pipe between 
Rossby and Derecho isn't there consistently.  The rtstats(1) plots for Derecho 
show that sometimes a lot of data gets through with little or no latency and at 
other times not much gets through will a lot of latency.  This is consistent 
with a lot of highly-variable traffic that's not related to the LDM 
crowding-out the LDM traffic.

Regards,
Steve Emmerson
