Please look at the following items when you encounter the errors: * Logs on the VNC server(s). * Enable debug logging for guacd and look at guacd logs around the time of disconnect, and see if there are additional errors logged? * Load of the guacd server at the time of the disconnect - is it experiencing high load (memory, network, CPU)? * Load of the VNC server(s) when they disconnect - are they experiencing high load of any kind at the time of disconnect? * Network traffic at the time of disconnect - what are the characteristics of the network between guacd and the VNC servers? Is there any high latency or bandwidth utilization at the time of the disconnects. -Nick
