Hi  
I have used spawn pluggin successfully in my test rails project(will  
use in original) for spawning process  
[http://rubyforge.org/projects/spawn/](http://rubyforge.org/projects/spawn/)

My controller code as below  
class UserController \< ApplicationController  
def create  
t=spawn do  
sending\_mail\_function(@user)  
end

def sending\_mail\_function(user)  
d=LateNotice.deliver\_late\_timesheet(user)  
end

end  
end

LateNotice is classs derived from action mailer…My question is suppose  
sending mail function failured how can I track that?Just for example  
after clicking mail send button i ahve to send 3 mails to a particular  
user. I am disconnecting the LAN cable(just for example)…So in that  
case also a new spawn id is returned and the execution after spawn will  
continue…But actually mail not send…How can I track this in above
