Package: x2goserver

Version: 4.1.0.3

Hi,

It's really quite variable.

I can go weeks without having a problem and get my session back every day, as it can happen every morning when I want to resume my session?

Server:

When a session is crashed, I can't log in:

"

"

x2goclient --debug in attached file:

Can you help me, please ?

Is there any way to make sure it doesn't happen again?

Or a solution to force the resume?

Hello,

After a small adjustment of the size of /dev/shm in the fstab, it was 
running quite well since 1 year...


But it started again since a few days:

Does anyone know how to resume a session in this state?
