GitHub user lhotari added a comment to the discussion: Issues with Topic-Level 
Policies after Cluster Restart in Pulsar 3.0.5

> Is this a known bug in Pulsar? If so, in which version was it fixed?

Yes.

* https://github.com/apache/pulsar/issues/24436

The problem might be caused by BookKeeper data loss issue 
(https://github.com/apache/bookkeeper/pull/4607) fixed in BookKeeper release 
4.16.7 / 4.17.2 included since Pulsar 3.0.13, 3.3.8 and 4.0.6 releases.

The latest supported Pulsar releases are 3.0.15, 4.0.9 and 4.1.2, so it's 
recommend to upgrade to one of the supported versions.

That might be a viable option in certain cases. Please check the issues for 
possible workaround.

Make sure to run an up-to-date version of Pulsar. There are hundreds of bug 
fixes since 3.0.5 release. If you run on an old version, you might be running 
into issues that have already been addressed.
