Dear Wiki user, You have subscribed to a wiki page or wiki category on "Httpd Wiki" for change notification.
The following page has been changed by noodl: http://wiki.apache.org/httpd/HttpreadyAcceptFilter The comment on the change is: Formatting cleanup ------------------------------------------------------------------------------ - You may get the following error while starting Apache on freeBSD system: + You may get the following error when starting Apache on a FreeBSD system: - [warn] (2)No such file or directory: Failed to enable the âhttpreadyâ Accept Filter + {{{[warn] (2)No such file or directory: Failed to enable the âhttpreadyâ Accept Filter}}} - This happens because accf_http kernel module is not loaded. This module buffers HTTP connection and prevents the application from receiving the connected descriptor via accept until either a full HTTP/1.0 or HTTP/1.1 HEAD or GET request has been buffered by the kernel. This effectively reduces the amount of required CPU utilization to handle incoming requests by keeping active processes in preforking servers such as Apache low and reducing the size of the file descriptor set that needs to be managed by interfaces such as select, poll or kevent based servers. + This happens because the {{{accf_http}}} kernel module is not loaded.
