This issue happens, in my case, when the connection drops and Pika handles the error. This results in the on_connection_closed callback getting called which I have instructed to stop the connection.ioloop. I think the problem is that if you have a nested poll()s you end up with nested handlers so even if the poller (i.e. the while loop in poller.start()) </span><span>is stopped</span><span>, when the call stack unwinds you can end up with calls to poll() getting executed as a result of a transport.rpc(). Does this make any sense?<br></span></div><div><br></div><div style="font-family: times new roman, new york, times, serif; font-size: 12pt;"><div style="font-family: times new roman, new york, times,

That is peculiar. What is the duration of time between the stop and pending event? Is an exception being thrown? Do you have a traceback?</div><div><br></div><div>Gavin</div><div><span class="yiv1455757913Apple-style-span" style="color:rgb(160, 160, 168);"><br></span></div><div><span class="yiv1455757913Apple-style-span" style="color:rgb(160, 160, 168);"><br></span></div><div><span class="yiv1455757913Apple-style-span" style="color:rgb(160, 160, 168);">On Thursday, October 20, 2011 at 12:55 PM, E Hope-Morley wrote:</span></div>

When I call SelectConnection.ioloop.stop() following a connection drop on my connection, it sometimes fails to actually stop the ioloop i.e. following the call to stop(), a callback may sometimes be called in response to a pending event.
