I compiled newest apache 2.4.1 with "--enable-mpms-shared=all". Three mpm modules are there.(mod_mpm_event.so, mod_mpm_prefork.so, mod_mpm_worker.so". LoadModule mpm_event_module modules/mod_mpm_event.so is default enabled. But i start apache by "apachect -k start", the message is: AH00534: httpd: Configuration error: More than one MPM loaded. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
