When fetching long outputs through SSH using programmatic libraries such as AsyncSSH or GOLANG SSH
1) Increase the SSH window size (the issue could not be reproduced after changing the window size to 131072): ip ssh window-size 2) Configure: ip ssh bulk-mode
The issue is not seen in IOS-XE releases starting from 17.10 where 'ip ssh bulk-mode' is configured by default.
