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.

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?

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.
