Gabe,

The product-queue was on an NFS-mounted disk from a remote system.  This
caused the problems you encountered (the product-queue file is
memory-mapped by the LDM server and this isn't supported by NFS-mounted
filesystems).

I removed the data/ symbolic link to

    /nfs/polarmet8/data5/langbauer/ldm/data/

and recreated the data/ subdirectory as a real directory of the LDM
user's home-directory.  This works.

I also added symbolic links in the (now real) data/ subdirectory to the
conduit/ and EXP/ subdirectories in
/nfs/polarmet8/data5/langbauer/ldm/data/.  Accessing those directories,
however, is extremely slow.  So, if the LDM is decoding into those
directories, then the performance might be unsatisfactory and you might
want to reify those subdirectories in the new data/ directory.

You'll also need to edit the files etc/ldmd.conf (to request data) and
etc/pqact.conf (to process the data).

Regards,
Steve Emmerson
