What have you done so far to eliminate that as the cause? Given the
[fundamental nature of the feature in
question|http://guacamole.apache.org/faq/#probably-not-a-bug] and the
uniqueness of what you're doing here, some unexpected behavior of that "Docker
-> socat -> Docker" portion seems more likely.

... to avoid exposing the port ...
{quote}
If Guacamole is running beneath Docker on the same machine as TigerVNC, I'm not
sure what you're trying to avoid exposing. Any Docker container on that machine
will be able to connect to your TigerVNC using the IP address of the Docker
interface.

[jira] [Commented] (GUACAMOLE-709) Possible Client Memory Leak

Should this sawtooth pattern be normal?
{quote}
The sawtooth pattern of heap consumption is normal for any Java application,
yes. Under normal, healthy operation, you will see heap consumption grow until
it reaches a threshold where the JVM performs a GC.
Here's a decent post going over the characteristics of leaky and non-leaky
graphs:
https://plumbr.io/blog/memory-leaks/memory-leaks-fallacies-and-misconceptions
{quote}
I realize it's doing garbage collection at the tip of the sawtooth but why is
it growing?
{quote}
Java will not free up heap immediately. It waits for what the JVM deems is an
opportune time to perform a GC and free up heap. What you are observing is not
the heap _growing_ but the heap being _used_, which just about every Java
function call will do. If heap usage were growing, the valley of the sawtooth
would be gradually higher each time.
You may see some different behavior with newer JVMs with respect to the nature
and timing of that GC, but what you're seeing here is normal and not indicative
of a leak.
If you still suspect a leak, what you need to do is run things with VisualVM
through multiple GC cycles (probably several hours at the rate shown in your
graph), and see whether the graph still looks healthy.
