Hi Tom,

Regarding ldmd.log, from your message I'm confused.  When you do 'touch
ldmd.log' in /usr/local/ldm/logs, you should get a 0 length file.  Does
that happen?  

Two things are required for the logging to occur.  First, the log file
must exist even if it's empty.  Thus, the 'touch ldmd.log' must
succeed.  And, 'touch ldmd.log' should be done as user 'ldm' so that the
file is owned by ldm. 

The second requirement is that the syslog daemon knows where to write
the ldm's messages.  That is, certain entries must be in the file
/etc/syslog.conf. Instructions for how to modify this file can be found
in http://www.unidata.ucar.edu/packages/ldm/ldmPreInstallList.html under
"Configuring the Operating System as root".    

If you've done all this already and are still having problems, then
ownership and permissions may be wrong.  What are the permissions on
/usr/local/ldm/logs, and who owns the directory?

Regarding dostats and mailpqstats, I see from the code that mailpqstats
wants ldmd.log to be present.  So, if you get the logging working it
might fix this problem too.  If it doesn't we'll look further into this
problem.  Let me know what happens.
