I managed to catch the issue again on another test. Same backtrace:
```

```
Nearly the same scenario (with some re-transmissions for bad conditions
simulation). And now sometimes (not always) I catch also this in logs:
```

No problems with MySQL again, only when using PostgreSQL instead and only with
pua/pua_reginfo
