Hi, 2.2.25 crashes on FreeBSD with a kqueue-related message. I see references to something similar (http://www.dovecot.org/list/dovecot/2012-February.txt) from a couple years ago. I get: Jul 1 10:07:27 imap dovecot: master: Panic: kevent(EV_ADD, READ, 54) failed: Bad file descriptor It's not dumping core, and I get the message even with "protocols =" Downgrading back to 2.2.24 fixes it. What info would be helpful for me to provide here? # Adam -- Adam Weinberger adamw at adamw.org http://www.adamw.org

...d guess the hangs caused by recent RC versions were because the default was to use notify=kqueue instead of notify=none. I changed this back to none unless --with-ioloop=kqueue is used. There are a couple of things in the code that I'm not completely sure of. The kqueue() manual page says that EV_ADD "modifies" the event if it already exists. What exactly does that mean? Does it mean that the filter is replaced, or that it's ORed into the existing one? The same question for the EV_DELETE, does it delete everything or only those filters given in parameters? The code currently assu...

The attached patch should fix the problem with dying imap on "Unrecognized event". The problem is that when we register a handle for IO_ERROR only, we still can get readable/writable event without EV_EOF being set.
