Fair enough. I have been having problems with having enough memory for bayes operations. In an attempt to resolve them, I've gone back to my v0 bayes database. Is there any way to do an expiry run on a v0 database with 2.60 without upgrading the DB to v2? I'd like to pare down the size of the DB before I upgrade.
Can it be done with an earlier version of SA?
Not sure the answer to your question there, but I see a reply from Theo.
When I upgraded from 2.55 to 2.60, I followed the suggested method -
I already used DB_File so I didn't have to worry about converting it, I just did an sa-learn --rebuild under 2.55, then installed 2.60, then did another sa-learn --rebuild.
I seem to remember that the second one of those which would have caused the database format to be converted from v0 to v2 took about 10 minutes on a Pentium 4 2.4Ghz, and consumed at one point about 600MB of ram on a 1GB ram machine.... (there were a few minutes of worry watching it happening :)
Mind you I think our Bayes database at the time had well over 300,000 emails learnt...
One other thing I forgot to mention is that a bus error could possibly be triggered by a process exceeding the set process limits as controlled by ulimit. (Note that it was zsh reporting the bus error) Not sure if ulimit -a works in zsh as well, but thats what you'd check with in bash...
