Title:
Cells connecting pool tracking
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) juno series:
Fix Released
Bug description:
Cells has a rpc driver for inter-cell communication. A
oslo.messaging.Transport is created for each inter-cell message.
In previous versions of oslo.messaging, connection pool references
were maintained within the RabbitMQ driver abstraction in
oslo.messaging. As of oslo.messaging commit
f3370da11a867bae287d7f549a671811e8b399ef, the application must
maintain a single reference to Transport or references to the
connection pool will be lost.
The net effect of this is that cells constructs a new broker
connection pool (and a connection) on every message sent between
cells. This is leaking references to connections.
