Knowing how to reproduce this would help. Adding retain_last_statements=100 and dump_last_statements=on_error would show the previous SQL executed before the error is logged. |

Added some extra logging to the next 2.3 release that'll show the latest session command whenever one of these messages is logged. That in addition to retain_last_statements=100 should help reveal what is going on. |
