[Mimedefang] bayes error

[Mathew Thomas]

Hi All,

I have got four mail gateways running Solaris 9 with Sendmail 8.13.1+ mimedefang-2.44+SpamAssassin 2.64. Each server
handle about 50,000 mail per day, there is no inbox in the server. I am always having problem with bayes in all the
gateways. 

My bayes configuration in sa-mimedefang.cf:
bayes_auto_learn        1
use_bayes       1
bayes_file_mode 0666
bayes_path /var/spool/bayesian/bayes
auto_learn_threshold_nonspam    0.1
auto_learn_threshold_spam       8.0


$>sa-learn --rebuild

I could fix it by deleting the files, "bayes_journal", "bayes_seen",  and "bayes_toks". Then it will run without any
problem for few days.
How can I fix this? 

Thanks
