Is it ready to review? If yes, you can remove the "WIP" from the title.

Could you try the `streamnative/sn-pulsar:2.9.2.17` image? It looks more like a Pulsar side problem. There should be some fixes since 2.9.1 but I didn't remember the specific PRs. In addition,...

Sorry I'm busy with other tasks recently, I will take a look at these logs soon.

It still looks like a Pulsar side bug and triggered by the bundle split. You can try to reproduce it with bundle split disabled and see if it will still...
