[SR-Users] Need help troubleshooting messages that never made it to the client

[Andrew Chen]

Hi Daniel,

Thanks for the response.  The question that's been raised by our engineers
is how do we know the message that's put in the queue actually successfully
been sent on the wire/network?  Have there been situations where it gets
stuck in the queue and never sent out?

Thanks.
