Hi,
I have a question on the way to use Berkeley db in Cyrus.
As you may see, some body posted on a problem that imapd hung.
I found it several times whenever massively testing Cyrus with
postfix/smtpstone with '-L' (lmtp) option.
I think it would be a locking problem caused by Berkeley db engine.
The locking problem comes from various situation:
(1) some lmtpd/imapd dead by interrupt(11, 9, or other)
(2) some potential bug (sorry, I am not sure)
I think that there should be a dedicated process managing mailbox db
to avoid such problems.
So I tried to compile Berkeley DB with 'rpc' option and
modified the Cyrus imapd to use Berkeley db rpc server(bundled single thread version)
At that time, imapd goes also hung.
I don't know yet what caused such a problem.
Any comment would be appreciated.
