The above message contained the following:

Interesting.  Good news!  And it's consistent with a third-party
being the cause of the problem (e.g., a firewall or router).

You must be running the LDM in verbose mode.

These messages are printed by a downstream LDM when it's upstream LDM
hasn't communicated with it for 1 minute (an upstream LDM will try to
communicate at least every 30 seconds).

You're logging to the system log file rather than to an LDM-specific log
file.  That's unusual.  We recommend using a separate log file for the
LDM system because of the volume of log messages and the occasional
need to wade through them.  More information can be found in the "LDM
Basics" webpages for your version of the LDM at
