Describe the bug
RocksDB occasionally (?) crashes with _ZN7rocksdb6DBImpl11NewIteratorERKNS_11ReadOptionsEPNS_18ColumnFamilyHandleE+0x14f
I noticed that tests got flakier on CI, tried to repro, tests succeeded on all local runs but I noticed the error log.
To Reproduce
No idea. Ran the tests for the bookkeeper-server, tests do retries.
When I checked later the test run reported success but I noticed the error dump (attached)
Expected behavior
No crash
