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
