Package: x2goserver
Version: 4.0.1.20

The client machine's OS: Windows 10 The client machine's version of X2GoClient: 4.1.0.0-2017.03.11 Any relevant session settings in X2GoClient: XFCE or KDE session 
The server's OS: Centos (3.10.0-514.el7.x86_64) 7 

The server's version of the x2goserver package: 4.0.1.20 

After a few hours of running a certain tool (Cadence - unfortunately not open source), we see a sudden slowdown where the whole session reacts very very slowly and screen refreshes also very slowly. The load on the server is not significant and the server also has plenty of memory. Sometimes, if we leave it alone for a few minutes, it can recover, but not always. If we open another session in parallel, that new session is fine.
