What's actually happening is that I get:-

    Cannot obtain lock file, aborting.

and then a few seconds later:-

    error: NNTP server went away (server disconnect or timeout)
    error: news.annexcafe.com: received bogus greeting (498): (nil)
    news.annexcafe.com: address list exhausted without establishing connection.
    error: NNTP server went away (server disconnect or timeout)
    error: news.easysw.com: received bogus greeting (498): (nil)
    news.easysw.com: address list exhausted without establishing connection.
    WARNING: some servers have not been queried!


This is fairly consistent.  The last two attempts that leafnode has
made to collect news resulted in exactly this sequence.  It can't be
that the lockfile directory doesn't exist as, most of the time, it
works OK.  It just gets these bursts of paranoia!
