[LDM #QAT-399075]: Pqact question

Hi Carissa,

That shouldn't happen. :-(

pqact(1) doesn't care if the data is corrupt. It does care if the product-queue 
is corrupt and will log that fact if it is.

> If the data is

Not from pqact(1). You might see something from the decoder to which pqact(1) 
pipes the product. Does the decoder log problems?

Both of these sequences work:

    www.unidata.ucar.edu -> Support -> Support Archives
    www.unidata.ucar.edu -> Software -> LDM -> Support -> Current Support 
Questions

They wind-up at the same place, which doesn't allow searches of the body of 
emails.

One can always do a Google search using the qualifier "site:unidata.ucar.edu" 
(e.g. "site:unidata.ucar.edu pqact insertion").

We tend to use Google here.

The "#011" in the above concerns me. It would appear that the 
product-identifier contained a vertical-tab control character. Could this have 
caused the relevant pqact(1) configuration-file entry to not be triggered?

Would you please send me the relevant pqact(1) configuration-file entry.
