I'm using slightly modified Cyrus 2.1.17 on a Woody with DB3 3.2.9-16 ---
No problems at all using it with mailboxes, deliver, tls_sessions. No
tweaks or other special configurations. Did/do have the occasional POP3
bind ups but that doesn't seem to be BDB related....though I haven't really
tried that.
POP3 bind ups -- occasionally, without reason, POP3 stops working. It
never banners. I've been unable to reproduce it, and it requires a
complete system reboot to recover, so it's something with saved state of
somesort. I don't think it's BDB because that's all automatically
recovered on restart so there shouldn't be a deadlock situation there
between cyrus stop/starts.
