The bfd decay test is known to be flaky with ASan. Ilya had mentionned it initially when enabling ASan: https://mail.openvswitch.org/pipermail/ovs-dev/2021-February/380467.html More recently, Eelco mentionned it: https://mail.openvswitch.org/pipermail/ovs-dev/2022-September/397476.html I also see it every once in a while in GHA.

Do I need to take care of the intel-ovs-compilation pipeline?

Hi Stefan, I don't think any action is needed on your part at this time. And I think (but am not entirely sure) we can ignore the intel-ovs-compilation error.

In some cases ovsdb server or relay gets restarted, ovsdb python clients may keep the local socket open. Instead of reconnecting a lot of failures will be logged. This can be reproduced with ssl connections to the server/relay and restarting it, so it has the same IP after restart. This patch catches the Exceptions at do_handshake to recreate the connection on the client side.
