{Yeah, well, I gave up and let mkhistory crank for a few hours...}

Well - yes, now that you mention it - this is now the _only_ 386
I have left. I wouldn't have thought that to be pertinent, but what
do I know :-) The machine only has 8 meg of memory, and it too is the
smallest.
I do have an old 386sx-25 laptop w/ 8 meg. I can install 2.1.5R
there and test anything you want to try out - although it wouldn't
be my news spool and so wouldn't get too exercised.
I have yet to see the problem anywhere else...

That would explain that...

Naw - I'm basically conservative in what system software I run. I've
been coddling along the version of Cnews I got in 1988 (at one time, I
even ran it on a '286 with XENIX.) It doesn't do anything near as
sophisticated as mmap'd active files.. :-)
I think all it's really doing is reading, creating and deleting a *lot*
of files...

p.s. Thanks for the response - I was beginning to wonder if my messages
were being thrown out with the bath-water... Sure is a lot more
traffic these days...
