[rabbitmq-discuss] Problem: NOT_FOUND - no binding between exchange 'xxxxx' in vhost

[Scott Durgin]

Thank you for investigating. So far with the upgrade we have not been able
to reproduce, but will be keeping a keen eye on this for sure.

For purposes of helping with better information, is there a way to increase
debug logging information that we could turn on and provide if we can
reproduce this (or other issues).

Thanks again for the prompt response.

Unfortunately there's not much to go on here, but this does sound like it
has some features in common with a bug we fixed in 3.2.0. So if anyone sees
this behaviour with >= 3.2.0 I would be very interested to hear about it,
but otherwise I am inclined to leave it.

Cheers, Simon
