[X2Go-User] x2go occasionally stops responding

I can connect to my x2go session running XFCE on CentOS 8.1. The x2go client runs on Windows. Screen updates are still pushed to my client correctly (on-screen clock shows correct time), however sometimes my kb and mouse actions start being ignored. I can disconnect and reconnect to the same session from another windows PC and the results are the same. So something on the CentOS server appears to be the issue, The only way I know to recover is kill the x2go session on the server and reconnect.
