Hi,
I set up x2gobroker with SSH proxy with passwordless authentication
(auth on broker and proxy, not auth at x2goserver). Now I want to get
the session resuming fixed. Everytime I connect, I get one additional
session while disconnecting results in a suspended session. After a
couple of days, my x2goserver runs out of memory and therefore becomes
very slow.
