[Mimedefang] Bayes errors in logfile

[Cormack, Ken]

Group,

I've just awakened AWL, and global bayes auto-learn in MIMEDefang, and I'm
seeing the following errors, in my log.

Aug 12 10:53:52 mail01 mimedefang-multiplexor[9340]: Slave 9 stderr: lock:
9340 unlink of temp lock
/var/spool/MIMEDefang/bayes.lock.mail01.mydomain.com.9340 failed: No such
file or directory

Aug 12 10:53:52 mail01 mimedefang-multiplexor[9340]: Slave 9 stderr: Cannot
open bayes databases /var/spool/MIMEDefang/bayes_* R/W: lock failed: No such
file or directory

And like this...

Aug 12 11:27:12 mail01 mimedefang-multiplexor[22720]: Slave 6 stderr: lock:
22720 unlink of temp lock
/var/spool/MIMEDefang/bayes.lock.mail01.mydomain.com.22720 failed: No such
file or directory Cannot open bayes databases /var/spool/MIMEDefang/bayes_*
R/W: lock failed: No such file or directory

In my /var/spool/MIMEDefang directory, I see the following relevant files:

total 33604
drwx------    6 defang   defang        340 Aug 12 11:07 .
drwxr-xr-x   19 root     root         4096 Aug 12 10:56 ..

>From time to time, I also see a lockfile called something like
"bayes.lock.mail01.mydomain.com.SOME_PID", with perms of 0600, u=defang
g=defang.

The bayes configuration lines in my sa-mimedefang.cf look like this:

# Enable Bayes
use_bayes            1
use_bayes_rules      1
bayes_path           /var/spool/MIMEDefang/bayes
bayes_file_mode      0700
bayes_auto_learn     1

Does anyone have any ideas or suggestions?  Mail seems to be flowing, but
I'm concerned/confused about the logged errors.

This system is RH 8.0, with sendmail 8.13.4, MIMEDefang 2.52, and
Mail::SpamAssassin 3.000004

Thanks in advance.

Ken
