Hmmm, might be that you have an issue because your child's child is 
attached to your ruby process once the starter process stops.  There is 
a whole range of other possible issues causing this which is hard to 
sort out given the little information we have.  Did you take proper 
measures to demonize your child process after fork?

Kind regards
