Despejo principal não legível após falha de segmentação

Question

Eu tenho o seguinte problema na minha pilha LAMP(hp) , de tempos em tempos recebo Segmentation fault . Então eu fiz core dump no meu Debian Squeeze e eu esperava que ele me dissesse alguma coisa, mas isso não me diz nada:

Reading symbols from /usr/sbin/apache2...Reading symbols from /usr/lib/debug/usr/sbin/apache2-mpm-prefork...done.
(no debugging symbols found)...done.
Core was generated by '/usr/sbin/apache2 -k start'.
Program terminated with signal 11, Segmentation fault.

Que abordagem devo tentar encontrar para o problema?

    

Answer 1

Você deve compilar o apache com a opção -g no conjunto CFLAGS. Se você usar qualquer módulo apache de terceiros, também deverá compilá-los com a opção -g. Confira este link para mais informações
