I you allow me to log on as the LDM user, then I can do most of the
upgrading for you.

The "-flush" option will ensure that the data is written to
disk.  The "-close" option will do that and also close the
file.  Closing the file means that it will have to be reopened
if another data product has to be appended to the same file.
Opening a file is a relatively costly operation.

> The ldmd.log file is empty.

You should fix that.  See 
<http://www.unidata.ucar.edu/software/ldm/ldm-current/basics/preinstallation.html#syslog.conf>
for instructions.

I believe that the error that caused your LDM to terminate
is fixed in later releases.
