thanks for your help with this.

I'm going to try installing guacamole manually tomorrow. Regarding the responsiveness of the server, when this issue occurs, the server will stop responding to pings, the console will become unresponsive, and esxi will report a spike in CPU usage for the host. Guacamole's interface will no longer respond either due to the loss of network connectivity.

I'm trying to set up guacamole to allow html5 ssh access to my server. so far I've done the following:

1. apt-get install guacamole

Though this is unlikely to be related to your problem, I would recommend installing a recent release of Guacamole following the manual, rather than installing packages via apt-get.

3. Restarted Guacd and tomcat

After doing all of this, I'll be able to login to guacamole's web interface and get presented with "Login:" on guacamole's web terminal interface, but then my debian installation (clean install aside from guacamole, open-vm-tools, and ssh) just becomes completely unresponsive and won't respond again until I perform a hard reboot. I'm running Linux kingston 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux.

Does the lack of response correlate to logging in to Guacamole?

When the system is unresponsive, does the Guacamole interface respond (page can be reloaded, you can log 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 something in my configuration that's incorrect? I checked syslog and catalina.log, but they both just stop logging at the same time that my system becomes unresponsive. 

It's unlikely that anything in Guacamole could cause your system to go entirely down like this. Since "unresponsive" can mean many things, I think the first step here is to determine exactly what condition occurs on the server to result in that behavior.
