Experience the same problem with: OS X 19.9.4, Mac client X2Go Client V.4.0.2.0 (Qt - 4.8.5) On the remote server I see one CPU completely killed: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 21002 filer 20 0 63148 41m 5528 S 66.5 1.7 3:51.08 x2goagent 21323 filer 20 0 20936 4956 2516 S 15.3 0.2 0:53.50 xfce4-settings- 21303 filer 20 0 20336 8688 7120 S 0.7 0.4 0:02.84 xfwm4 21305 filer 20 0 35364 10m 8976 S 0.3 0.5 0:00.72 xfce4-panel At the same time, as soon as I disconnect. CPU usage of x2goagent goes to 0. Is it the case that Linux clients don't have this problem? thank you, Kirill
