Does the lack of response correlate to l= ogging in to Guacamole?

When the system is unrespon= sive, does the Guacamole interface respond (page can be reloaded, you can lo= g out / back in successfully, etc.)?

To what degree= is the system unresponsive? Does the server respond to input via a hardware= keyboard? Does the server respond to pings?

Is there somethin= g in my configuration that's incorrect? I checked syslog and catalina.log, b= ut they both just stop logging at the same time that my system becomes unres= ponsive. 


It's u= nlikely that anything in Guacamole could cause your system to go entirely do= wn like this. Since "unresponsive" can mean many things, I think the first s= tep here is to determine exactly what condition occurs on the server to resu= lt in that behavior.
