We have a user complaining that his screen sharing cuts off unexpectedly. When I check the flashphoner_manager.log I see a storm of the following lines keep repeating forever:

Hello

Try to disable manager RMI
Code: 
disable_manager_rmi=true
It should prevent errors in flashphoner_manager.log

Regarding error.
If you can reproduce this, try to update to the latest version 3511
https://docs.flashphoner.com/display/WCS5EN/Release+notes
and enable debug log on user's session according this guide:
https://docs.flashphoner.com/display/WCS5EN/WCS+Core+logs#WCSCorelogs-Logginglevelmanaging"onthefly"
Once you packed logs, please send to support@flashphoner.com
We will check.

In latest versions REST Hooks do not use RMI and works directly from WCS Core process.
So yes you can set disable_manager_rmi=true
As a side effect, Monitoring UI will not work.
REST Hooks will work.

Please send output of 'show apps' in CLI on port 2001 and WCS configs (archived dir) and logs to support@flashphoner.com. Or, if possible, send credentials for ssh access to the server.

screen sharing cuts off unexpectedly
Click to expand...
Please let know if the issue does still occur.

There are many "Failed to encode compound RTP packet to send" exceptions in the server logs. The exception was fixed in build 5.1.3531.
Please try updating to the latest version 5.1.3571.
