I just compiled dovecot2 on my ARM Sheevaplug system. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195168 But, your panic should not have to do with dovecot. Applications are not supposed to make the kernel panic. It normally is the kernel itself which makes it panic. Does disabling superpages help? Put vm.pmap.sp_enabled=0 in loader.conf or sysctl.conf. Other people mentioned a problem with that the previous days. NB: what version of FreeBSD are you running? Regards, Ronald.
