Note that this is probably related to [Bug#4498](http://bugs.proftpd.org/show_bug.cgi?id=4498).

Note that as of [Bug#4443](http://bugs.proftpd.org/show_bug.cgi?id=4443), TLS renegotiations are _disabled_ by default. That said, having TLS logging that helps to pinpoint TLS issues related to renegotiations (when enabled) would still be...

I have seen, in the past, issues with TLS transfers that seem to be related to TLS renegotiations. I notice that in your `mod_tls` configuration, you have: ``` TLSOptions AllowClientRenegotiations...

Ah. Would it be possible for you to try a newer ProFTPD version, 1.3.7b at least (or later)? I ask because the filename behavior you mention reminds me of the...

OK, so this issue you are seeing, is specific to the FTPS client (Chilkat?) that you are using, correct? Other FTPS clients work as expected? Did adding `TLSRenegotiate none` as...

I see. I think the underlying issue is Issue #1171. The port numbers of data transfers are reused, but in a bad way, because of that bug. And the issue...

This might be trickier than I'd like. The reason is that `ftptop` only displays data stored in the ProFTPD scoreboard file. This scoreboard uses a custom fixed-record format; the size...

Do you have a Redis service running, as is done [here](https://github.com/proftpd/proftpd/blob/master/.github/workflows/ci.yml#L22), for use by those Redis unit tests? If not, that might explain that test failure. (Or it could be...
