At work, on our RHEL 6.5 64-bit server running GNOME2 and X2Go Heuler
over the last several months (X2Go is updated monthly) (My default
shell is TCSH for legacy reasons):

Once I observed every process under my x2go session using up tons of
CPU. I had to kill those processes.

I do not think I have observed x2goagent/nxagent using up tons of CPU,
but it has 8 physical cores so it is not noticeable if only 1 is maxed

The client has been X2Go Client 4.0.1.x and on Windows 7 SP1
64-bit. I am running a full GNOME xsession.

I have observed this problem all the time on the aforementioned server
& client. My workaround is to disconnect & reconnect frequently (or to
use Cygwin X11 manually tunneled over SSH.)
