Lighttpd не перезапускается чисто (адрес уже используется)

Когда я недавно выполнял dist-upgrade, моя установка lighttpd-1.4.19 на Ubuntu 8.0.4 перестала корректно перезагружаться или перезагружаться с помощью команды /etc/init.d/lighttpd restart.

~$ sudo /etc/init.d/lighttpd restart
 * Stopping web server lighttpd
   ...done.
 * Starting web server lighttpd
2009-06-13 04:06:36: (network.c.300) can't bind to port:  80 Address already in use 
   ...fail!

Та же ошибка возникает при перезагрузке.

Я могу обойти это, чтобы убить lighttpd, а затем запустить команду запуска, но, похоже, мне не следовало этого делать :)

Я просмотрел свои файлы конфигурации и не обнаружил немедленных ошибок. Есть ли у кого-нибудь идеи, что может вызвать эту ошибку? Кажется, это последняя версия на момент написания этого вопроса, доступная по маршруту apt-get.
