[Mimedefang] Issues with updating Bayes v2 to v3

[Richard Whelan]

Hi,

I've got two new machines, with SA 3.0.3 & MD 2.52, replacing two
existing systems, with SA 2.64 & MD 2.43. I want to use the existing
bayes DBs as they have been built up over quite sometime. On Monday I
tried to use the db-to-txt perl script, which was expanding nicely, but
after creating a file of over 10Gb, I decided to kill that off and just
try to use the sa-learn process instead. That has now been running for
over 24 hrs. Would it normally take this long to convert ?

One other problem I've seen is on an identical system, which wouldn't
even recognise the bayes_toks file as v2 at all. It came back with :

debug: bayes: 16992 tie-ing to DB file R/O
/var/spool/MIMEDefang-bayes/bayes_toks
Cannot open bayes databases /var/spool/MIMEDefang-bayes/bayes_* R/O: tie
failed:

where as the system that is still converting gave:

debug: bayes: 13295 tie-ing to DB file R/O

The bayes DBs on the new machines are using the same files taken from
the same machine, so why is one seeing it the other failing ?

Thanks,

Richard
