If you're finding your FastCGI application is exhausting your VPSs memory, try something like this in your httpd.conf: {code} FastCgiConfig -minProcesses 1 -maxProcesses 2 -processSlack 1 {code} 1 Resolving Permission Denied Errors Getting errors like this? {code:none} [Sun Oct 23 01:51:06 2005] [crit] (13)Permission denied: FastCGI: can't create (dynamic) server "/var/www/html/test.fcgi": bind() failed [/var/log/httpd/fastcgi/dynamic/b6430285f5b9734eda3a466e975355c3] [Sun Oct 23 01:51:11 2005] [alert] [client 60.234.162.14] (13)Permission denied: FastCGI: failed to connect to (dynamic) server "/var/www/html/test.fcgi": something is seriously wrong, any chance the socket/named_pipe directory was removed?, see the FastCgiIpcDir directive [Sun Oct 23 01:51:11 2005] [error] [client 60.234.162.14] FastCGI: incomplete headers (0 bytes) received from server "/var/www/html/test.fcgi" {code} I found one mail (http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/83308?help-en) about the problem. If I set "FastCgiIpcDir /tmp" in httpd.conf it resolves the problem. The better solution is to probably figure out the permissions (symlink?) issue. 2007-03-17 21:51:53.0 2005-09-02 23:05:33.0
