Timeout won't reset after the first time out happened

Question

I expected that timeout will happen every 30 seconds in the following code:

def action_with_timeout(threshould, &block)
  begin
    Timeout::timeout(threshould) {block.call}
  rescue Exception => e
    ap("Timeout #{threshould}, stop loading pag, #{Time.now}")
    stop_loading_page
  end
end
while true
  action_with_timeout(30) {
    ap("to INDEX")
    browse_to(CONFIG["ROOT_URL"])
  }
end

However, it only works for the first time. The remaining will timeout in a short time. The output is:

"Timeout 30, stop loading pag, 2015-07-01 19:59:10 +0800"
"Timeout 30, stop loading pag, 2015-07-01 19:59:13 +0800"
"Timeout 30, stop loading pag, 2015-07-01 19:59:16 +0800"
"Timeout 30, stop loading pag, 2015-07-01 19:59:19 +0800"

How can I fix it?

Are you sure the exception is a timeout exception and not something else? — Frederick Cheung, Jul 01 '15 at 12:04
You should look at what exception it gets by `puts e` before `ap(..)` — Smar, Jul 01 '15 at 12:06
Also if you want to catch only the timeout exception, use `rescue Timeout::Error => e` instead. — Smar, Jul 01 '15 at 12:07

rescue Exception will rescue any exception (it's a bad idea to do so).

Be specific in order to rescue the exception you're interested in:

require 'timeout'

def action_with_timeout(sec, &block)
  Timeout::timeout(sec, &block)
rescue Timeout::Error
  # ...
end

Other exceptions will not be rescued. This should reveal your actual problem.
