Hi Tim,

OK.

Very good.

OK, so the pattern in the pqact.conf pattern-action file has an error in it.

re:
> The line in question is the following:
> 
> NEXRAD  ^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)

The problem is most likely that some of the whitespace in pattern-action
file actions are tabs, not spaces.  Written to accentuate the location
of tabs, your entry will look like:

NEXRAD<tab>^SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
<tab>FILE<tab>-close<tab>data/nexrad/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3

The solution is to edit your pattern-action file and replace the spaces
with tabs as indicated by the accentuated listing.

re:
> This was the line I copied from the pqact file from another working ldm, so
> I am confused as to why there is a problem with the syntax.

If you cut and pasted the entry from a terminal window, it is likely
that the tabs were replaced/interpreted as spaces.

re:

After making the editing changes listed above, check the integrity of
your pattern-action file actions again using:

<as 'ldm'>

ldmadmin pqactcheck

If there are no errors indicated, you should be able to start your LDM
without errors.

Cheers,

Tom
