+====== Steps to trouble shoot rails application errors under LiteSpeed ======
+If your get errors from a rails application under LSWS, please try the following trouble shooting steps:
+  * Make sure the rails application works well under WEBrick or mongrel running as the user who own the application.
+  * Some Rails application depends on certain environment variables, LiteSpeed only set "PATH" to "/usr/local/bin:/usr/bin" by default, all other shell environment variables are stripped, you may need to set extra environment vairables under "Server"->"Ruby Rails" tab matching that are under your shell envirnment. For example, RESTful route depends on "HOME" environment variable.
+  * Double check file permissions for your rails application directory.
+  * Make sure Memory and process limits have been set high enough under "Server"->"Ruby Rails" tab.
+  * Check Rails log file, LSWS stderr.log in addition to error.log under lsws/logs directory.
+  * Try reinstalling ruby-lsapi via gem or manually if you found anything abnormal in stderr.log
+  * Check your DB configuration for the mode Rails running as, switching between "Production" and "Development" mode.
+  * Turn on LSWS debug logging by change "Debug Level" to "High".
+  * strace the rails process, locate the PID of ruby process with command "ps -ef | grep ruby", then strace them with command like "strace -p <pid_of_ruby_Process>". You should strace the child ruby process which actually handle the request.
