This week when we upgrade apache2.0.50 to 2.0.53, httpd processes suddenly get killed by a segfault as seen below in the error_log: Mon Feb 14 17:14:26 2005] [notice] child pid 16788 exit signal Segmentation fault (11) [Mon Feb 14 17:14:26 2005] [notice] child pid 16787 exit signal Segmentation fault (11) [Mon Feb 14 17:14:27 2005] [notice] child pid 16789 exit signal Segmentation fault (11) [Mon Feb 14 17:14:28 2005] [notice] child pid 16802 exit signal Segmentation fault (11) [Mon Feb 14 17:14:28 2005] [notice] child pid 16801 exit signal Segmentation fault (11) [Mon Feb 14 17:14:28 2005] [notice] child pid 16800 exit signal Segmentation fault (11) [Mon Feb 14 17:14:28 2005] [notice] child pid 16791 exit signal Segmentation fault (11) ...
