Please add the configuration directive that sets /app/apache2/logbrowse-logs/apache_runtime_status. That makes it easier to find the module that tries to create the shared memory. here's the directive: <IfModule !mpm_netware.c> <IfModule !perchild.c> ScoreBoardFile logbrowse-logs/apache_runtime_status </IfModule> </IfModule> |
