Or I'm wrong? > So, if I understand what you're saying correctly, you're hitting a limit of 60 *concurrent* connections - that is, a single guacd instance running in Docker cannot open more than 60 connections at the same time? Some of the previous issues we saw (but that have been fixed) were not with concurrent connections, but with accumulated connections - that is, you could open and close a connection 60 times, and the 61st try would fail, even if no other connections were active. Just want to clarify the scope of the problem, here. I'm trying to get some infrastructure set up for running some test environments for various Guacamole issues, and I'll have to see if I can reproduce this and get 60 concurrent connections open. -Nick >
