it's great for heavily loaded servers, because constantly recompiling
that damn file with multiple processes tends to corrupt it.
Eh? Rebuilding it while multiple processes are accessing it corrupts
it?!? Or multiple processes trying to rebuild the same file?
I believe it's multiple processes trying to rebuild the same file. I've
had a corrupted cdb for a long time - from courier POP auths. I've
never fixed it because I also have the mysql patches, and SMTP Auth in
place.
Everything works, so I'm not touching it until I completely rebuild that
system :)
I love qmail too, but I'm with ya on all the 'unapproved' patches and
it's concurrency limitations.
The mysql side of things could be alleviated by using sqlrelay. Don't
hammer mysql. Hammer sqlrelay instead :)
Oh EXCELLENT tip. I thought replicating the database to each server was
the best solution, sqlrelay looks like it'll make things even better.
Thanks Christopher
