Can anyone explain what this error mean? The CG client stopped working completely and had to restart the server. It was like it blocked all image and template commands. A playout client on the same machine was running without issues.
I have this also in my project
(my fault 
)
This happens when you send too many commands to the server at the same time.
Or when something has blocked the execution of a command such that it never finishes executing and you keep sending commands after that.
That sounds more like the issue I experienced. The client sends keystrokes in real time to templates and never had that issue even in low end hardware so some specific command was causing that.
