Hi,  
Yesterday we started migrating our project to Rails 2.2.2. For one of  
the Ajax Request I faced some problem.  
When I click an AJAX link, then in the UI I can see my rhtml code  
directly like

\<% \_\_in\_erb\_template=true %\>  
\<%= render :partial =\> “manage\_availability”%\>

And in the console I got this.

Host: [harish.example.com:3009](http://harish.example.com:3009)

After this my total server is gone.  
That time I am getting “500 Internal Server Error”.

/!\ FAILSAFE /!\ Sat Dec 27 15:49:47 +0530 2008  
Status: 500 Internal Server Error  
Invalid new\_session option:

Did any one faced this problem? What kind of issue is this? Why the  
server is going?

The interesting bit are the lines following this. Follow the  
stacktrace until it meets your own code and you might be able to  
workout what’s happening.
