- Does it happen to all users of the Guacamole install, or just this single
user?  If it's only happening to one user, and other users are fine, then
it probably isn't an issue with Guacamole, the server, etc.
- If a single user, where is that user connecting from?  What are the
characteristics of the network link?
- Does it happen to connections to a specific server or servers on a
specific network?
- Are guacamole-client and guacamole-server (guacd) running on the same
system or different systems?  If different, is the network link between
them over-loaded or very high latency?
- Is the server running Guacamole, either the client, guacd, or both,
running under heavy load or experiencing any issues that would cause delays
in processing the traffic?

Examine the various characteristics of the systems and connections and try
to figure out where the commonality is in the users or systems exhibiting
the problem, and work from there.  There are many people using Guacamole
without issue, so I doubt the problem is with Guacamole itself (at least,
the software portion), so try to figure out where it is an work to resolve
whatever resource problem is causing it.
