Brian this is a resource issue with Guacamole, here is a rule of thumb we use below.
For every 10 connections vCPU x2 4GB RAM 1000Mbps Nic We run over 2000 connections at once spread out over 4 Guacamole server for various colleges and corporations. Specs look like this: Per Guacamole instance vCPU 8x8 (64 cores) 128G RAM 100GB SSD 1000/10000Mbps Networking Hope this helps Thank You Sean Hulbert Founder / CEO Work Ph: 925.663.5565 Security Centric Inc.

Epitoma Rei Militaris From: Brian Filipek [mailto:[email protected]] Sent: Monday, August 22, 2022 11:54 AM To: [email protected] Subject: RE: Re: Guacamole on Chrome OS 103/104 ARM Hi Mike, After I posted I verified my message did show up on the list. I had checked it every day for at least a couple weeks. Nobody had responded to it but it was on the list. Now my message doesn't show up in any search. At any rate, we have hundreds of Chromebooks of all models, also a few computers running ChromeOS Flex. When the problem does happen it happens on these machines only. We cannot reproduce it on a Windows machine. I have seen these disconnects happen in two different situations: - When a user connects to a terminal server from Guacamole, if that user happens to have a disconnected session on that terminal server, it will result in immediate disconnection the moment you try to connect. Once this problem happens, we can RDP into the terminal server from a Windows machine using the built in Windows RDP client, log the user off of the server, and then the user will be able to log back in using Guacamole on their ChromeOS/Flex device. - If the user is running an app on the terminal server, sometimes moving the scroll bar on the app causes immediate disconnect of the session. Seems like there is some type of rendering conflict between Guacamole and Chrome on Chome devices. Again, we've only been able to reproduce this on ChromeOS/ChromeOS Flex devices using Guacamole in Chrome.
