The detailed stack is recorded at apache/bookkeeper#4457.
As Pulsar 3.0 is the most popular version for users who want to follow up to the community branch, we select 3.0.5 and try to upgrade to it. While testing 3.0, we meet such a fatal error. I think it is worthwhile for us put in time to solve it.
