[Message part 1 (text/plain, inline)]

Good morning everyone,

I'm seeing the exact same behaviour on my setup:

Host:
Springdale Open Enterprise Linux 8.2 x86_64

x2goagent.x86_64           4.1.0.3-5.epel8.playground
x2goserver.x86_64          4.1.0.3-5.epel8.playground
x2goserver-common.noarch   4.1.0.3-5.epel8.playground                
x2goserver-xsession.noarch 4.1.0.3-5.epel8.playground                

Client:
Springdale Open Enterprise Linux 8.2 x86_64

x2goclient.x86_64          4.1.2.2-1.epel8.playground


Session freezes when idle for a few minutes, and nothing can bring it
back. There is nothing in the session.log file on the host, and nothing
on the client either.
But on the host, in /tmp/.x2go-tba/C-tba-58-
1593751325_stDXFCE_dp24/cmdoutput I see a lot of errors:

Not entirely sure these are related though. I've attached the whole
file.

Any advice is appeciated.

Thanks,
