Hi Ben,
Thank you for the answer. I’m using open stack Victoria deployed with Kolla-ansible. 
So I assume I should add (in /etc/kolla/config/global.conf)

[oslo_messaging_rabbit] 
heartbeat_in_pthread = True


But for Victoria (nova sample configuration file) it seems to be deprecated?
# DEPRECATED: Run the health check heartbeat thread through a native python
# thread by default. If this option is equal to False then the health check
# heartbeat will inherit the execution model from the parent process. For
# example if the parent process has monkey patched the stdlib by using
# eventlet/greenlet then the heartbeat will be run through a green thread
# (boolean value)
# This option is deprecated for removal.
# Its value may be silently ignored in the future.
#heartbeat_in_pthread = true
So will it work?

Best regards
Adam Tomas

This sounds like you're hitting the heartbeat/eventlet bug. Basically eventlet won't schedule the heartbeat thread unless something is regularly waking up the api threads. Depending on what release you're running, you may be able to set heartbeat_in_pthread[0] to fix this.

Hi,
after some struggling I have almost „clear” logs (clear=error free :) ) Almost…. RabbitMQ keeps disconnecting sessions and there is a huge amount of disconnect errors in all logs (see below). I found this bug description:
https://bugzilla.redhat.com/show_bug.cgi?id=1711794 <https://bugzilla.redhat.com/show_bug.cgi?id=1711794>
in which we can read as follows: "this is a recoverable issue that is already handled by how oslo.messaging is designed. disconnection is not an error and should not be reported as such in the logs.”
but… It is reported :( And produces tons of logs.
I tried to modify heartbeat values - helped a little bit, but I had to increase [database] max_pool_size = 5 and that of course multiplied number of disconnection errors by 5 :(
[oslo_messaging_rabbit]
heartbeat_timeout_threshold = 720 heartbeat_interval = 360 heartbeat_rate = 4
How to avoid this disconnections?? Or what to do to avoid writing this „errors”to logs?
Best regards
Adam Tomas
