What were you trying to do that didn't work?

Connections from or to containers that were started with passt-0^20251210.gd04c480-1.el9 are stalling sometimes - usually for a certain on source or target, while other connections are working fine.

We have seen both IPv4 and IPv6 connections being affected.

Some connections stalled always, some most of the times and some were even flapping more.

Restarting the container (or even the host), didn't change anything.

Downgrading passt to passt-0^20250512.g8ec1341-2.el9.x86_64 and restarting the container makes the connection working again.

Upgrading passt back to passt-0^20251210.gd04c480-1.el9 breaks connectivity again.

What is the impact of this issue to you?
