Troubleshooting • sftp get fails with kernel messages

Hi all,
I am trying to sftp get files from an RPi Zero W to an RPi 3 B+. It worked for the first two files, but now always stalls. Any help would be appreciated.

Thank you,
Scott

RPi 3 B+ running Buster, sftp to the RPi Zero W:
uname -a
Linux RPiDevSys 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux

On one terminal, I run sftp to the RPi Zero W
sftp> get -p 240303_015829.jpg
Fetching /home/micam/Pictures/240303_015829.jpg to 240303_015829.jpg
/home/micam/Pictures/240303_015829.jpg 46% 800KB 0.0KB/s - stalled -^

On another terminal, I run ssh to the RPi Zero W
Output shown below...
