There's your problem. Somehow your watermark got set ridiculously high, or
the news server decided to re-number all their articles into a much lower
range, and from now until the end of eternity, you're not going to find any
"new" articles to pull out of the newsgroup and post to the list.
You're going to need to reset that watermark, if you want to get things
You would need to talk to your news server administrator to see if they did
a re-numbering, or silently switched you to be pointed at a different news
server with a different article numbering, or what.
This is one of those cases where it helps to be the administrator of both
sets of systems, so that you know what's going on under the hood on both
ends of the connection, and you have full control over what changes are or
are not made.
BTW, if you were using a server-style feed mechanism, there wouldn't be a
You would instead track incoming messages by their message-id and date
headers, and if the message had a recent enough date header to be within
your chosen window of operation, and you had not seen that message-id within
that window of operation, and the message in question was posted on one of
the newsgroups you're subscribed to, then you'd accept the message.
No watermarks here.
Of course, you continually purge old message-ids out of your database, but
you do want to keep them for a while after the window has expired, in case
someone takes an old feed and tries to re-submit it -- you want to be able
to reject all those old re-posted articles.

Mark Sapiro would be a much better person to have that part of the
discussion with. He's the lead developer for the 2.1 "stable" branch, and
he would be able to tell you what you might need to do.
