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?
gdb backtrace: http://dovecot.org/bugreport.html#coredumps
Fuller logs attached. Thanks for your help, Timo.

Weird. I haven't touched anything even close to that. Also kqueue works on my OSX. The only thing that comes to my mind is https://github.com/dovecot/core/commit/fde7b8a03bf91cfa5bb7ca3e84545386243fa...
Does it happen to work if you use the attached patch?
Looks like its an issue on OpenBSD -current as well.
