Hi Vidar, Scott,
I got that error while incorrect connecting attempts to ZRAPI from python - SSH login from nodejs/python .
API proccess takes about 27% of CPU for a long time and won’t allow to connect again until restart zoomroom App.
Looks like ZRAPI waits for socket data, cannot destroy socket and refuses any connections.
Now the installation works stable with correct python/ssh implementation, but I think the issue is still here.
