With bounce processing, not sure if it's related or different issue, but we're seeing it getting stuck in Cron-Running every single time the CRON runs. It works if we use emergency actions.
Having tested this in SSH, what we're seeing is that after the first run it seems lose the bounce server, which I assume is why it gets stuck in Cron-Running?
Here's the SSH output:

Once it's lost the server ID 3, it never picks it back up again, which is why I assume that's what's causing the Cron-Running to get stuck on every process.
What's weird is this is happening on only one out of three installations of MW.
Any ideas?
