Gilbert,

If you havn't done so yet, I would try building 5.2 from source on
weather2.  In fact, when I run into LDM problems with a binary
installation this is always the first thing I do.

Other than building from source, I would try to put the LDM into
verbose logging at the 6 hour mark.  Perhaps the verbose logging will
shed some more light on the group leader rpc.ldmd exit.  You change
the LDM logging verbosity by sending the group leader rpc.ldmd
a USR1 signal.  The first 'kill -USR1' ups the logging level to
verbose; the second to debug; the third goes back to silent.
