Actually, I'm archiving in realtime and batch becomes a bit messy. I'll up
the
number of LOCKTRIES and LOCKDELAY.
I think batch updates are not messy. I believe several users have
set up methods to do this.
After switching from real-time to batch updates I found many fewer
problems with corrupt indices and bogus lock files. Since there aren't
any locks in contention, things work much better.
I also reduced the span of a particular volume to try and keep the index
size less than 1000 messages, to make life easier on my modem-based
users (which is most of my population).
Between these two measures, I haven't had a MHonArc related problem in
about 11 months (knock on electrons).
