Server side service did restart, i did not have to manually restart the service after the failure. I had a red windows warning on the file move, i just hit try again and it completed.

It looks like your SMB session was disconnected mid-stream in a server-side copy due to receiving a SIGTERM signal. As the memory for SMB session was being freed the destructor function for what was an in-flight copy-chunk request was called and hit an assertion. So code behaved as designed, but it's unclear why the session closed (perhaps SMB server restart while data in-flight).
Got a core file created and smb crash while moving files between 2 shares.
Let me know if more information is required.
