Hi Gilbert, David, and LDM users,
The source of the "duplicate" products that Daryl and Mike Z were
discussing was the NOAA Weather Wire (WxWire) feed that Fox13 TV is also
ingesting on the same machine on which NOAAPort is being ingested.
WxWire ingestion has been turned off temporarily, so the source of the
duplicate products has disappeared.
We are evaluating what the best course of action is given that a
product sent via WxWire can be different as far as the LDM is concerned
(i.e., different MD5 signature) from the "same" product sent in
NOAAPort. Ugh!
Cheers,
Tom

True, but they may have been doing additional testing related to this.
When they did the testing last week, they had some significant issues…

Changing the underlying network shouldn't cause duplicated products.
(For example, the network equipment knows nothing about the data
headers and would have no possible way of producing the extra strings)

I can confirm that double product looks the same for me, complete
with LOX-846094 at the end of the second. I'm not sure which site
was feeding that at the time though.

Greetings,
Over the past couple of hours, I have noticed a problem with
product text over IDD including what appears to be a debug tag
at the end of the product. For example:
WWUS76 KLOX 041650
Came at 2022-03-04T16:50:36Z with 2026 bytes and again at
2022-03-04T16:50:38Z at 2038 bytes. The second product had
the following at the end of the text:
&&
$$
LOX-846094
That "LOX-846094" appears to be some debugging string with the
transmission of the product? Looking at the my IDD logging, I
see:
wxengine4.fox.com
<https://urldefense.com/v3/__http:/wxengine4.fox.com__;!!DZ3fjg!o1bK4FJaMKZ5_t1qEkELlilHYevjZtBWwmCexGZCYVOlLAXVgqyWlw_XQSVerSLGBg$>
as the ingest source of this product. Anybody know anything
about this?
