   @mjsax @hachikuji My previous investigation on this issue ended up in the broker-side `DefaultRecordBatch#setLastOffset` which could some time set garbage into the byte buffer (sometimes deterministic but incorrect values, sometimes total random values), and after 36+ hours of chasing this lead I came to the conclusion that it is not really a bug in our code but more likely my IDEA's rabbit holes.. for example yesterday night with rebasing I managed to be able to run 500+ without failure and I peeled off each of the changes I made and it still succeeds, while this morning being on top of trunk #8400 it again fails on 170+ runs, and with all of this observations I'd have to say so long with my past two days and that this is likely not related to any issues on broker or consumer side..
