In my webserver, after accessing the rails application the dispatch.fcgi is not terminated properly...

While starting accessing a web page written in rails, dispatch.fcgi process is starts running,

After closing that web page also the process is not getting terminated...

what should i do to over come this problem.,

Because of this many dispatch.fcgi starts running in couple of hours, and atlast the server gets hang ( the process is not releasing memory, and also occupies the processor ).....
