It's just an internal thing. There's no network traffic associated with the "Session upkeep".

Okay – thanks much.
Could the massive amount of "Session upkeep" traffic be causing the server to try to kick me off after about 30m minutes?
Is the mass "Session upkeep" traffic typical for all SFTP clients?

Re: debug SFTP connection
All of that is normal with Debug-level log file.
The server-side bugs are also normal with OpenSSH server. They are not related to your problem.
I do not see anything unusual in the log. Sorry.
And there's no "ECONNRESET" error either.
Regarding the Passphrase: No – it says that the passphrase was not provided upfront. What is not even possible in UI. It can say "Yes" only in scripting.

debug SFTP connection
Martin, can you debug my SFTP connection to the host? I need to show them something for THEM to fix because they blame me on the problem. I'm getting intermittent errors, which sometimes blocks connection or transfer. I use a key file + passphrase to authenticate.
My IDE shows "Error: read ECONNRESET" and FileZilla sometimes shows the same.
Got a few questions from the log file:
1) What is a "Detected network event"? Is this normal or does it indicate something abnormal happened?
2) Is it normal to have a massive amount of "Session upkeep" entries, like 2 per second?
3) Is this a typical thing, is it a possible issue in my case?
Also, a potential bug:
I do use a passphrase but the log file says: "User name: myusername (Password: No, Key file: Yes, Passphrase: No)"

We believe the server has signed timestamps bug
We will use UTF-8 strings until server sends an invalid UTF-8 string as with SFTP version 3 and older UTF-8 strings are not mandatory
Also, a potential bug:
I do use a passphrase but the log file says: "User name: myusername (Password: No, Key file: Yes, Passphrase: No)"
