[Dovecot] bug in 1.0RC2?
Hello,
I have a small problem with dovecot 1.0RC2. This didn't happen with former versions. There are imap processes that are left open a long while after the client disconnected. I am running dovecot on OpenBSD 3.8. Below is the output of a process list. As you can see, there are many imap processes for the same login running.

I forgot: I'm running TLS, too. But the problem happended already with previous versions, too.

I must admit I didn't try _without_ TLS
For me it didn't appear in 1.0 beta versions (or at least I haven't seen it). But with RC2 it became problematic with more than 500 imap processes for few users.

I have the same problem with RC2 too, using TLS.

fbsd6.1, dovecot using TLS. --with-ioloop=kqueue solved the problem.
dovecot --build-options Build options: ioloop=kqueue notify=kqueue openssl SQL drivers: Passdb: checkpassword pam passwd passwd-file Userdb: checkpassword passwd prefetch passwd-file static
I noticed in rc1, the default for --with-ioloop is kqueue but in rc2, it changed to poll.

fbsd6.1, dovecot using TLS. --with-ioloop=kqueue solved the problem.

I noticed in rc1, the default for --with-ioloop is kqueue but in rc2, it changed to poll.

Hello,
I have a small problem with dovecot 1.0RC2. This didn't happen with former versions. There are imap processes that are left open a long while after the client disconnected. I am running dovecot on OpenBSD 3.8. Below is the output of a process list. As you can see, there are many imap processes for the same login running.
