From 2.0.8?
Jan 13 18:57:13 master: Error: service(imap): child 40100 killed with signal 11 (core not dumped - set service imap { drop_priv_before_exec=yes })
Is there a configuration change or something else I should have done while updating?
No.
I tried to get some information by loading the binary into gdb and got this:
(gdb) bt full #0 0x00000008007c71fc in kevent () from /lib/libc.so.7
It's difficult to guess what the problem could be without a usable gdb backtrace, and you need a core file for that. In FreeBSD the easiest way would probably be to enable kern.sugid_coredump sysctl. http://dovecot.org/bugreport.html has more info.
