Espero que alguien pueda ayudarme a depurar mis errores de Apache2. Por alguna razón, últimamente recibo muchos errores en uno de mis sistemas:
Sat Oct 10 16:49:24.101959 2015] [core:notice] [pid 18380] AH00051: child pid 2126 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
[Sat Oct 10 16:50:35.178108 2015] [core:notice] [pid 18380] AH00051: child pid 1971 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
[Sat Oct 10 16:50:43.188837 2015] [core:notice] [pid 18380] AH00051: child pid 2413 exit signal Bus error (7), possible coredump in /tmp/apache-coredumps
Intenté depurar con gdb, pero no tengo idea de cómo proceder después de soltar gdp en mi coredump. Esta es la salida de gdb:
