That's pretty much what I assumed, but wanted to confirm, thanks.

Oh great, something else to be confused about! <g>  This is the first
I've heard of nfssafe locking.  Per the recommendations in
spam.assassin.prefs.conf I set 'lock_method flock' in
/etc/mail/spamassassin/local.cf (see below) Note that it is commented
out in spam.assassin.prefs.conf.  If it should be uncommented as well as
added perhaps that should be added to the commments as it's not clear to
me at least if they're co-dependent or if one overrides the other.

snippet from spam.assassin.prefs.conf:

# If you are using a UNIX machine with all database files on local

a

adding
# the line "lock_method flock" to the /etc/mail/spamassassin/local.cf
# file. This is strongly recommended if you're not using NFS, as it is
# much faster than the NFS-safe locker.

I guess from the above settings.  Are there other settings I should be
looking at?  Suspect I have something screwy somewhere because I
generally have a bayes.mutex file, and the bayes_journal file seems to
appear now and again, but rapidly disappear.  If I delete the
bayes.mutex file it comes back rather soon.  The two outputs below were
seconds apart.

Thanks guys...
