не может перезапустить apache2 отказ сегментации

У меня есть апач установки и phpmyadmin, прежде чем phpmyadmin установил моего апача, хорошо работают, но после того, как установка phpmyadmin мой апач не может запустить и перезапустить с ошибкой как это

 * Restarting web server apache2                                         [fail]
 * The apache2 configtest failed.
Output of config test was:
Segmentation fault
Action 'configtest' failed.
The Apache error log may have more information.

у меня есть попытка искать ту же проблему в Google, но я не могу найти ту же ошибку.

этот мой журнал ошибок:
