No.. lock failures for the R/W bayes lock are normal, unless you're using
the journaled learning option for SA.

Basically this message means an opportunistic event that updates the bayes
DB was tried, but another event was already writing the bayes db. These
oportunistic events are autolearning and automatic expiry, and it's
reasonably common for them to collide. Rather than logjam the mail queue,
SA just notes it failed to lock the DB, and skips the autolearn or
postpones the expiry till later.

However, this shouldn't happen every time an email autolearns or the
database tries to expire. So, keep an eye on things. As long as
autolearning still happens sometimes, and your database isn't growing to
insane sizes without ever shrinking, you're OK.
