The above message contained the following:

> 11.

If you can, would you please send me a dump of the stack trace of the
core file?

> This, of course, killed off our whole ldm which is rather

I have no idea.  Just out of curiosity, what version of the LDM are you
running?

See

    
http://my.unidata.ucar.edu/cgi-bin/getfile?file=/content/support/help/MailArchives/ldm/msg03679.html

I would save the script as "util/exec-wrapper" relative to the LDM
user's home directory.  The util/ subdirectory should be in the PATH of
the LDM user.  Ensure that the script is executable.

Modify the LDM configuration file to use the script instead of the
pqbinstats(1) program.  Replace

    EXEC "pqbinstats"

with

    EXEC "exec-wrapper pqbinstats"

That's all.
