Bug Description

A bit of context: we have an Openstack Ussuri deployment (HA) on Ubuntu Focal. Most Openstack services are running on LXD containers on 3 baremetals. There are also two OVN-dedicated-chassis which act as gateways and nova-compute nodes.
A couple of days ago we updated all the packages in the environment to the latest versions (baremetals and lxc containers).
After the updates, we started seeing problems with the Octavia API. The API would randomly give an internal server error. Octavia API is running under Apache2 WSGI on 3 LXD containers on 3 separate nodes.
Looking into one of the Octavia container under /var/log/apache2/octavia_error.log, we found the following error:

The original /usr/lib/python3/dist-packages/octavia/api/config.py file is added to the bug report.
As seen in the file, the first line starts with a comment, but python is trying to run it as code.
Removing the first 5 charactersin the file so that string above starts right after the comment yelds the following traceback:

It seems that when the source file is read by python, the first 5 characters are skipped for some reason.
Digging deeper, I see no reason for importlib to trim those characters. Internally it uses _io.open_code().read() which should return the entire file without trimming anything

If adding the comment after the 5th char on the first line, the file is read as is should but the error moves to a different file:

As far as we can tell, this problem appears when importlib reads the file and hands it over incomplete (missing the first 5 chars).
This issue only occurs on the Octavia containers and not on the other Openstack services.
The other thing is that the fault is not consistent. It happens at Apache2 reload or restart but not everytime. Once in a few restarts. When the problem occurs, Octavia API is down.

Hello, we've narrowed down the problem to the upgrade of the python3-openvswitch package out of the 42 total python packages that were changed during the routine upgrade.
During the upgrade it went from 2.13.3-0ubuntu0.20.04.2 -> 2.13.8-0ubuntu1.1

In the release history of the openvswitch package of which python3-openvswitch is a dependency and is versioned together, 2.13.5-0ubuntu1 is the first version available after the package we had in the Octavia containers before the upgrade. It presents the problematic behavior and in the latest available version 2.13.8-0ubuntu1.2, it is still there.

We were only specifically testing what package change was causing Octavia API to hang (not the full loadbalancer functionality) as we've installed one python package deb at a time without dependency through dpdk.

This behavior can be replicated by having at least one loadbalancer object created in the Octavia DB and running 2-3 openstack loadbalancer list watch screens to query the 4 API workers under apache wsgi while reloading the apache workers every 60 seconds to stress as this does not happen every time, but it should be visible behavior under these conditions after 1-2 hours.

deb packages taken from:
https://launchpad.net/ubuntu/focal/amd64/python3-openvswitch/2.13.3-0ubuntu0.20.04.2
https://launchpad.net/ubuntu/focal/amd64/python3-openvswitch/2.13.5-0ubuntu1

This behavior also does not happen if the Octavia OVN provider is disabled with all the latest packages but with the python3-openvswitch downgrade it does not appear even with the OVN driver enabled.

Hello, we've narrowed down the problem to the upgrade of the python3-openvswitch package out of the 42 total python packages that were changed during the routine upgrade. 
During the upgrade it went from 2.13.3-0ubuntu0.20.04.2 -> 2.13.8-0ubuntu1.1

deb packages taken from:
https://launchpad.net/ubuntu/focal/amd64/python3-openvswitch/2.13.3-0ubuntu0.20.04.2
https://launchpad.net/ubuntu/focal/amd64/python3-openvswitch/2.13.5-0ubuntu1

This behavior also does not happen if the Octavia OVN provider is disabled with all the latest packages but with the python3-openvswitch downgrade it does not appear even with the OVN driver enabled.

This all looks a bit strange to me and I'm not sure about the causality of the findings presented.

FWIW; in the OpenStack Charms project the Octavia OVN Provider driver is enabled from Victoria onwards, as we have found the Ussuri version to not work properly.

To confirm that it still works I just triggered a successful CI run [0] which deploys a OpenStack Victoria cloud, which includes the 2.13.8-0ubuntu1.2 openvswitch package, and performs an end to end test.

0: https://openstack-ci-reports.ubuntu.com/artifacts/673/887246/4/check/focal-victoria-no-amphora/6731e85/
