I am running Apache 2.0.52 on Windows 2003 Server. Frequently in my Apache error_log file I get a line like this: [Wed Mar 16 08:08:17 2005] [info] (OS 10054)An existing connection was forcibly closed by the remote host. : core_output_filter: writing data to the network Also, periodically on this server, Apache momentarily stops handling requests, causing a page cannot be displayed message. I have reason to believe these two phenomena are related, because I can make requests to certain pages on my site that cause both the error message in the log as well as the page cannot be displayed message on subsequent requests. I have added the following directives to my httpd.conf file in order to alleviate these problems to no avail: EnableSendfile Off EnableMMAP Off Win32DisableAcceptEx The documentation seems to indicate that adding EnableSendfile OFF should get rid of the core_output_filter: writing data to the network issue, but it hasn't worked for me. Does anyone have any ideas as to what might be causing this problem? --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
