Proftpd постоянно падает

Итак, proftpd-1.3.5_4, freebsd 10, ставился из портов. Становился и настроился без проблем. Запускаем и смотрим, что он работает

root@server:/ # /usr/local/etc/rc.d/proftpd start 
Starting proftpd. 
root@server:/ # /usr/local/etc/rc.d/proftpd status 
proftpd is running as pid 15734. 

Но через короткий промежуток времени он сам останавливается. В логах ничего по этому поводу нет.

Запускаем proftpd с выводом информации в консоль

root@server:/ # proftpd -n -d 9 -c /usr/local/etc/proftpd.conf

Alarm clock 

В интернете пишут, что данная ошибка (Alarm clock), лечится пересборкой порта. Добавляем в Makefile такую строчку LDFLAGS+= -pthread.
Затем make configure && make install && make clean и все ftp стоит не падает

Описание и обсуждение данной ошибки первая, вторая, рабочий конфиг
