|
#### Bug Fixes
|
||
|
|
|
||
|
|
* Process responsible for running the autoheal partition handling strategy
|
||
|
|
could run into a deadlock with its peers, preventing autoheal from completing.

GitHub issue: [rabbitmq-server#1346](https://github.com/rabbitmq/rabbitmq-server/issues/1346)
|
||
|
|
|
||
|
|
* Garbage collection of mirrored queue metrics on nodes that did not
|
||
|
|
host a leader or mirror for a queue affected delivery and acknowledgement rates.
|
||
|
|
This could result in rates being 0 or negative when they should not be.

|
|
|
||
|
|
* Stats emission could prevent queue mirrors from performing garbage collection
|
||
|
|
and consume memory even when they were empty.
