It is the PID.

Could that nnrpd be so old that it's in the previous day's news.notice?

Seems unlikely, but I think you can do that by removing the Perl filter

The root issue here is that innd is not reaping its children.  Why it's
not reaping its children, I have no idea; none of the code in that area
has changed in eons.  It's also a very strange thing to have suddenly
start happening.

The relevant code is PROCreap in innd/proc.c.  You might want to add some
sort of logging to that function to see if (a) it ever gets called and (b)
if it does, what it thinks it's doing when it does get called.

    Please send questions to the list rather than mailing me directly.
     <http://www.eyrie.org/~eagle/faqs/questions.html> explains why.
