can you verify the behavior with current OTP-27 version (or at least OTP-26, OTP-25)? this would allow me to increase priority of the issue.

I guess there is some race condition in your case emptying cache earlier. Can you provide a bit more of dbg out to illustrate better what happens before the error?...

Thanks for providing more details, I think it is enough. I was just curious because it looked like a race condition and a situation when channel is closed and removed...

related PR is merged. fix will be released in next emergency patches for supported versions. thanks for the report!

The extra adjust_window call you pointed out conflicts with window adjustment mechanism already included in ssh_sftp module. Above results with too many window adjustment messages being sent towards ssh SFTP...

solved with #9309. will be provided in upcoming patches for supported OTP versions.

can you try more recent OTP-26 version? preferably the latest - is the issue present with [OTP 26.2.5.12](https://github.com/erlang/otp/releases/tag/OTP-26.2.5.12) ?
