Chris,

When you ran from the command line, you used user LDM and from ldm home.
Just checking for sanity sake.


  My pqact.conf entry looks like this:

Here's an entry from our LDM, the entry is only on two lines, try putting
the ldmConnect parmeters on one line.  Try changing the dir
data/nwx/pubprod/zone to another dir or just a .   The syntax is correct
so it has something to do with the directory part.


# Zone Forecasts (FPUS5[1-6], FPCA52, etc.)
WMO     ^...... .... ([0-3][0-9])([0-2][0-9]).*/pZFP
        PIPE    /usr/local/ldm/decoders/ldmConnect -e .zone (\1:yy)(\1:mm)
data/gempak/nwx/pubprod/zone
