This was taken when I had only one user connected with just one active RDP session. These ulimit values are the same on both of my guacamole systems (1.4.0 and 1.5.4). I get more guacd processes listed as user connections rise. However, my system usually doesn't go beyond 20 simultaneous connections. It's hard to think it's a socket resource issue. I'll keep looking.
