Hi Robert,
Whether this is a bug in x2go or an issue with x2go interacts with PulseAudio, please a file bug with our bug tracker.
I have some comments I would like to add, and I will mention them there.
Also, the high CPU usage may be a separate issue.

This seems to happen a couple of times a week. We are on Fedora 27. and just upgraded to x2goserver-4.1.0.0-0.0x2go1.0.git20180129.1511.heuler.fc27.x86_64
Every so often the logs start filling up with these: Feb 9 09:28:33 erdos pulseaudio[2124]: [pulseaudio] main.c: User-configured server at localhost:41031, refusing to start/autospawn.
Should we remind users to uncheck the audio box when logging in?
I see there is bug 161, https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=161 and 1143, https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1143 that are quite old but perhaps related. here's a 'ps -auwx | grep x2go' when this happens:

You can see the server load gets a bit high: top - 09:29:24 up 6 days, 16:37, 4 users, load average: 2.22, 3.07, 2.84 Tasks: 383 total, 2 running, 295 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.8 us, 0.5 sy, 1.6 ni, 87.0 id, 9.8 wa, 0.1 hi, 0.2 si, 0.0 st KiB Mem : 24670328 total, 502868 free, 2891660 used, 21275800 buff/cache KiB Swap: 40959996 total, 40601596 free, 358400 used. 21282084 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3026 20 0 157764 12240 4772 R 41.2 0.0 0:00.07 x2gogetagentsta
So I'm forced to kill the PIDs.
After restarting x2goserver: Feb 9 09:32:37 erdos /usr/sbin/x2gocleansessions[4477]: user3-331-1517954980_stDMATE_dp32, pid 30861: cleaning up stale X11 socket file: /tmp/.X11-unix/X331

Side note, why does /var/log/dnf.log have these nightly? DEBUG Unknown configuration option: protect = 0 in /etc/yum.repos.d/x2go.repo
