Within my rails application, I make exactly one connection to a drb server,  
using following code:

&nbsp;&nbsp;def connect\_to\_drb  
&nbsp;&nbsp;&nbsp;&nbsp;DRb.start\_service #line no 29 of program  
&nbsp;&nbsp;&nbsp;&nbsp;begin  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@drb\_con = DRbObject.new(nil, 'druby://'+@drb\_ip.strip)  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@con\_type = 'drb'  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return @drb\_con  
&nbsp;&nbsp;&nbsp;&nbsp;rescue  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;@drb\_con = nil  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return nil  
&nbsp;&nbsp;&nbsp;&nbsp;end  
&nbsp;&nbsp;end  
&nbsp;&nbsp;  
And strangely it gives me following error sometime.I stress, only sometimes.  
I guess, I don't need to do "DRb.start\_service" to connect to drb server.But  
still, I would like to know the reason.

I am on Ubuntu dapper server edition.running ruby 1.8.4 and using mongrel +  
apache2.2 mod\_proxy\_balancer

SocketError (getaddrinfo: Temporary failure in name resolution):

Also, as a follow up,

I can very well, do "DRb.start\_service" from command prompt.
