Hi, Ajay!

Your process of updating server i.e. the following code:

        process=Process.new(obj)
        process.process_on()
        processed_obj=process.obj
        server.update_obj(processed_obj)

is taking different times to complete in the two threads. Hopefully, you
can fix this by trying to tweak the {{ sleep(6) }}. For example the
following code (of course in your version) may fix your problem:

#!/usr/bin/env ruby
children=[]
for i in 1..2
  children[i-1]=Thread.new do
    stop_flag = false
    puts "A new thread created----------------------" #line alpha
    while !stop_flag
      sleep(i)
      puts "inside loop----------------------"

      sleep(i==2?6:1)  # <<< This will fix your problem
      stop_flag = true
      next
    end
    puts "--A thread completed"
  end
  sleep 0.5  # <<< Try delaying creation of threads for short time
end
children.each { |t| t.join }


Regards, igor
