I may have had a similar problem. After a few days/weeks, connections through guacamole would take a long time. I could connect directly to the computers via ssh or rdp just fine from a different computer in my lan.
I realized RAM usage on my server hosting guacamole was very high, and it looked to not be directly related to guacamole processes. I restarted. And it's been working fine for months. My guacamole server is inside a virtual machine, this guest is also my web server, the host is also serving several different guests. I've monitored ram use periodically since, and it has remained at a reasonable level and I have not seen the problem return. I do not think it was a guacamole-specific issue.
