Very good.

Yes, because the station name included in the product metadata is
the issuing station, and that is not necessarily the reporting
station (KWBC can issues bulletins for multiple reporting stations).

See above.

The problem is one of understanding that the headers of the bulletins
in the datastream are not necessarily the same as the stations in the
bulletins.  You can convince yourself of this by watching the output
of the LDM 'notifyme' utility for products matching your pattern:

<as 'ldm'>
notifyme -vxl- -f "IDS|DDPLUS" -p ^SAUS

You will see in your listing LOTS of reports with the KWBC id.  Since you are
fileing those reports, you can look through them and see that the stations
contained in them _never_ match KWBC since KWBC is the issuing station/center,
not the station ID.

Take a look through your ~ldm/data/awos/KWBC.metar file to see what I am
driving ato above.

No worries.

In this era of LOTS of data, 400 MB is considered to be a _small_ queue,
not large :-)

OK, so a 400 MB queue is plenty big enough for what you are ingesting.

> - how many 'pqact' processes do you have running trying to process your Data

OK.

> 10

A very small number, indeed.

> - what is the age of the oldest product in your LDM queue
> Pqmon reports 7410 (~2 hours)

Looks good.

Cheers,

Tom
