When performing a heartbeat to rabbit (inside a nova-compute process), there is a greenlet error which causes a hard crash.
I'm not exactly sure what details are relevant, but can provide more info if there's something that will be useful!
This is on RHEL7 (essentially... somewhat custom image based on it)

```
-------------------------------------------------------------------------------
[Impact]
The Nova default value of heartbeat_in_pthread needs to be False for non-wsgi services otherwise they crash when attempting to send a heartbeat message e.g. in a greenthread like nova-compute. This backports the patch to Jammy/Yoga in Ubuntu.
[Test Plan]
* Deploy Openstack Yoga on Jammy
* By default a heartbeat is checked 2 times every 60 seconds
* Check /var/log/nova/nova-compute.log and ensure that do not see any "greenlet.error: cannot switch to a different thread" errors
[Regression Potential]
No regressions are expected as a result of this patch. |

[Impact]
The Nova default value of heartbeat_in_pthread needs to be False for non-wsgi services otherwise they crash when attempting to send a heartbeat message e.g. in a greenthread like nova-compute. This backports the patch to Jammy/Yoga in Ubuntu.
[Test Plan]
* Deploy Openstack Yoga on Jammy and ensure nova-compute has debug=True
* ensure "oslo_messaging_rabbit.heartbeat_in_pthread = False" by checking latest entry in /var/log/nova/nova-compute.log
* By default a heartbeat is checked 2 times every 60 seconds
* Check /var/log/nova/nova-compute.log and ensure that do not see any "greenlet.error: cannot switch to a different thread" errors
[Regression Potential]
No regressions are expected as a result of this patch. |

description |
When performing a heartbeat to rabbit (inside a nova-compute process), there is a greenlet error which causes a hard crash.
I'm not exactly sure what details are relevant, but can provide more info if there's something that will be useful!
This is on RHEL7 (essentially... somewhat custom image based on it)

[Regression Potential]
Changing the default to False will mean that while services not running under wsgi will be fixed, services that are running under wsgi will revert back to using their native threading method i.e. greenthreads which is considered suboptimal and in very loaded environments this could have a perceived impact
on api performance. A separate bug https://bugs.launchpad.net/charm-nova-cloud-controller/+bug/2073260 has been opened to address this. |
