Greetings --

My news server is using innfeed for the distribution of articles and
currently has an unlimited backlog which I wish to limit.

Here are my current innfeed.conf settings:

backlog-directory:              innfeed                 # relative to pathspool
backlog-rotate-period:          60
backlog-ckpt-period:            30
backlog-newfile-period:         600
backlog-limit:                  0
backlog-factor:                 1.10
backlog-limit-highwater:        0
dynamic-backlog-filter:         0.7
dynamic-backlog-low:            25.0
dynamic-backlog-high:           50.0
no-backlog:                     false

Is there a recommended size for backlog-limit?  Just looking at my backlog
directory, I've determined that a 1MB *.output file contains about 300 lines.
One of my peer.output files contains over 3 million lines.

Also, this particular peer is actually accepting most of the articles sent,
but I have another peer which is refusing or rejecting about half of the
articles sent (this peer's innfeed output file is about half the size of
the 3-million-liner).  Is there any way that I can determine why this
peer is refusing/rejecting articles so that I can optimize my newsfeeds

And one last question...backlog-rotate-period is undocumented in the
innfeed.conf man page.  I'm assuming the value is in seconds, but what
kind of "rotation" is it controlling?

Thanks for any recommendations.
