A couple of things come to mind...

First, the session disconnection, in this particular case, is managed
mostly by the RDP server and not Guacamole.  So, something on the RDP
server side is causing a delay in the disconnection of the session such
that it takes a few seconds for the session to actually close out.
Depending on what RDP server you're using, this could be caused by
processes shutting down, profiles being saved, or several other things.  My
suggestion would be to monitor the server during the time when you
disconnect and try to see what's happening.

Another possibility would be to make sure you're using RemoteApp (RAILS)
functionality, which may handle this type of disconnect situation a little
more cleanly.  Depending on your RDP server (Windows vs xRDP) your level of
success in using this will vary, but Guacamole does support this
functionality as long as the RDP server does.

RemoteApp (RAILS) may help you out with this - I'm pretty sure it's capable
of closing the remote connection as soon as the RemoteApp is closed.

Thanks for the update.
We found out that Windows RDP server was taking about that much time to
logoff, once the remote application is closed. What we found is it is a
default Windows behaviour and there is no configuration in Windows or
Remote Desktop Services, where we could change that. As a workaround, we
explicitly called logoff.exe on the exit of the remote application.
