apache2 вина сегментный: не может найти вызвать

Question

я получаю это записи журнала на Ubuntu 10.04 LTS:

# vim /var/log/apache2/error.log

Я добавил coredumps к моему httpd.conf:

CoreDumpDirectory /tmp/apache2-gdb-dump 

создали, CHMOD 777 и Чаун WWW-данные: WWW-СРЕДА tmp/apache2-dgb-dump установите

# ulimit -c unlimited 

и перезапустить Apache. CoreDump создан, и я попытался проанализировать его, но он не говорит мне ничего ...:

Что я могу сделать, чтобы выяснить, в чем проблема?

Вы используете gdb неправильно. Согласно выходу gdb, дамп ядра генерировался /usr/sbin/apache2. Вы должны запустить gdb следующим образом: gdb /usr/sbin/apache2 core. /etc/init.d/apache2 есть, скорее всего, некоторый скрипт, вызывающий /usr/sbin/apache2. См GdB вывод:

"/etc/init.d/apache2": not in executable format: File format not recognized
