WolfSSH 1.4.5 echoserver SFTP Error [-1001] "Channel data received" #311
Description
This might well be a problem between keyboard and chair but here it goes:
Server A:
OpenSSH_8.4p1, OpenSSL 1.1.1i 8 Dec 2020 Linux 5.4.89-gentoo
Server B:
Linux 5.10.7-0-lts wolfSSL/wolfssl#1-Alpine

on Server B:
Error with SSH shutdown.
Error [-1001] "Channel data received" with handling connection.
The error depends on file size. I tested files with sizes of 1KB, 10KB, 100KB, 1MB and 10MB.
1KB and 10KB files succeed.
100KB file uploads 96% and stalls.
1MB file sometimes succeeds, sometimes fails with Error [-1001] "Channel data received" with handling connection.
10MB file fails with Error [-1001] "Channel data received" or "verify mac error" with handling connection
I also tested with a Windows machine running WinSCP 5.17.9 and got Error [-1001] "Channel data received" as well.
Please let me know if you need more details.
