Description Bob SpamAssassin 2005-04-12 07:50:34 UTC 
Running Fedora Core 1.
Upgraded (via DAGs RPMs) from
spamassassin-3.0.2-1.1.fc1.rf.i386.rpm to
spamassassin-3.0.2-2.1.fc1.rf.i386.rpm.

Suddenly, much more spam is getting through. And, sa-learn does not appear to be 
learning.

Example, I run: "sa-learn --spam --mbox SpamMissed"

And get this: "Learned from 169 message(s) (169 message(s) examined)."

It usually does not learn from every message in the mailbox.

If I run it a second time, same message, no learning.

Perhaps the reason that more spam is suddenly get through is because the learner 
is broken and previous learning has been 'forgotten'?

Sounds very likely, and if your problem is a corrupt database (which can be
corrupted by a variety of O/S problems, not necessarily an SA bug), then a) the
easy fix is to wipe your Bayes database and start over, and b) you're more
likely to get more help from the SA users' list than through the bugzilla
system. I'd suggest report your problem there and see if that will help resolve it.

Triage on the database solved the problem, the db was corrupt.

Used the --backup and --restore options to complete the triage.
Will use the --no-sync option for all future training.

Thank you.
