Thanks noufal, I got it.
After gevent.spawn, we have to do join or gevent.joinall or gevent.sleep or patched library call to start the greenlets, right ? I have see the code which not using any of these after gevent.spawn, How it is working there ? https://github.com/Juniper/contrail-controller/blob/master/src/opserver/uveserver.py#L656 Thanks, On Sun, Jun 21, 2015 at 1:01 PM, Noufal Ibrahim KV <nou...@nibrahim.net.in> wrote: > On Sun, Jun 21 2015, anu sree wrote: > > > [...] > > > This code has two pause (gevent.sleep(0)), in Consumer.start and > > Worker.run.
