Temporary failure in name resolution

[hemant kumar]

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


def connect_to_drb
DRb.start_service #line no 29 of program
begin
@drb_con = DRbObject.new(nil, 'druby://'+@drb_ip.strip)
@con_type = 'drb'
return @drb_con
rescue
@drb_con = nil
return nil
end
end

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

Also, as a follow up,

I can very well, do "DRb.start_service" from command prompt.
