           Summary: Odd errors if tieing Bayes DB while learning...
           Product: Spamassassin
           Version: SVN Trunk (Latest Devel Version)
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Learner
        AssignedTo: spamassassin-dev@incubator.apache.org
        ReportedBy: felicity@kluge.net


In one window I have an sa-learn running, learning a few thousand mails.  In
another window, I do "sa-learn --dump magic -D" and get the debug output at the
bottom of this comment.  Notice it says the bayes db version is 0, but the bayes
db is definitely version 3.  It seems as if the tie works, but then trying to
read the db fails.  If this is this is the case, then we need to essentially
lock the db for reading (or have a collective read lock anyway) too, otherwise
the data we get could be corrupted.
