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.
