Approximate messages are not getting updated

Could not reproduce it. It is most likely happened because of some configuration issue.

[alok87]

So what is happening is -

Long Polling is done on a queueURI.

If a user specifies a wrong queueURI in the WPA resource, the long polling starts happening in that incorrect queueURI. And when the user redeploys the correct queueURI in WPA, it is expected that LongPoller will reconfigure itself for the new queue URI.

But this is not happening and this is the bug.

This is happening even when for the same queue a new WPA object is being created and the old one is removed. So until the WPA controller restarts the queue msgs are not getting updated.

[alok87]

So the new thread is not getting spinned up/refreshed for a new/updated WPA object

All the poller threads stop as soon as we delete a WPA object.

This Poller main goroutine Run is getting stuck or stopped when a WPA object is deleted
