**Is your enhancement request related to a problem? Please describe.** I sometimes see this error message: ``` 2021-01-14 20:40:03.388 ERROR [140107798095616] ClientConnection:891 | [<SOME_IP:PORT> -> <SOME_IP:PORT>] Failed lookup req_id: X error: 6 ``` I'm not sure what `error: 6` means specifically, and I can't easily tell from looking at the code. I can tell it originates from [here](https://github.com/apache/pulsar/blob/master/pulsar-client-cpp/lib/ClientConnection.cc#L903), but I'm a little lost trying to follow it any further. **Describe the solution you'd like** Have some explanation somewhere of what these error codes mean. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
