The above message contained the following:

So, the feedtype is NEXRAD2 (alias CRAFT) and the pattern is ".*".  OK.

How do you know that NEXRAD2 data-products stopped being inserted into
the product-queue around 15:21 UTC?

Those messages are normal for a pqact(1) process in debug mode.  When
a data-product matches the selection-criteria of a pqact(1) process,
then the process will log two INFO message and several DEBUG messages;
otherwise, it will only log two DEBUG messages (when in debug mode).

Were data-products of feedtypes other than NEXRAD2 also being inserted
into the product-queue?
