0.9.9 on Docker with Reverse Proxy Stable, 0.9.12 on Docker with Reverse Proxy Unstable
Docker host OS = Ubuntu Server 16.04.2 LTS
Docker version = 17.03.1-ce
Docker compose version = 1.13.0 jwilder/nginx-proxy
version = 1.13.0
Reverse proxy settings = jwilder/nginx-proxy default settings
Target connection = Windows 7 RDP
Network environment = LAN (http) & WAN (https)
In the environment above, 0.9.9 performs consistently. Connections
are made with the Windows 7 RDP target and are held until
In the environment above, 0.9.12 (and 0.9.11) performs
inconsistently. Connections are made with the Windows 7 RDP target
but last only approximately 5 minutes at which point the connection
is terminated for the following: "ERROR: User is not responding."
The attached screen shot of the guacd log is an example of the log
output. Docker-compose scripts that show how each environment is
built are also included.
Has anyone else experienced the same behavior? If so, is there a
workaround available that produces consistent 0.9.12 performance?

1. Hardware assisted virtualization exposed to guest OS.
2. vCPU increased from 4 to 8.
3. Anchored on 0.9.11 which is the latest version posted on the Docker hub by Glyptodon.
See below for for screenshots of network and CPU loads. Memory loads are not included as there is nothing significant occurring. Increasing vCPUs bumped up the max network load capability for 0.9.11 but the end result was still a disconnect. 0.9.9 network load escalated as well but connection remained solid.
Conclusion: 0.9.11 connection problems are not overwhelmed by an increase in CPU resources.
