Error communicating with the remote browser It may have died

I know this question has been asked many times and i have checked those but could not find solution .Above error is not frequent only sometimes i get it , so i am not able figure out why it is occurring .After executing below lines of code

 driver.get(first_url)
    #here i open forst url the perform some operation    
    main_window =driver.current_window_handle
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + "t")
    #above line opens a new tab 
    # Put focus on current window which will, in fact, put focus on the current visible tab
    main_window_new =driver.current_window_handle
    driver.switch_to_window(main_window_new )
    time.sleep(1)
    driver.get(second_url)
    #opening new tab in the existing browser 
    time.sleep(2)
    json_str=driver.find_element_by_tag_name('body').text
    time.sleep(1)
    print json
    # Close current tab
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')

    # Put focus on current window which will be the window opener
    driver.switch_to_window(main_window)

Because the below line will close your browser if it has only one tab open.

# remove that line and run your code. You will not see this error again.
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')
