I posted this on Fedora's Bugzilla, https://bugzilla.redhat.com/show_bug.cgi?id=1881488 but it was closed. Not sure if X2Go or Gazebo is the problem.
Running the following:
gazebo-11.1.0-2.fc33.x86_64, 5.9.16-200.fc33.x86_64
From top:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
167977 myuser 20 0 19.6g 325912 148004 S 882.6 0.2 5:33.38 gzclient
And from strace, wouldn't all of the "Resource temporarily unavailable" be troublesome?
