[X2Go-User] Hanging Session

Hello everybody,

I've running X2Go (v4.0.1.20) on CentoOS6 and it works quite well.

Last week I was out of office and I kept a session running on the 
"server". When I came back, I was not able to connect to session again. 
The client stucks after starting the connection, after >1/2h I killed 
the client.
When I try to connect afterwards, I have to suspend the session 1st, 
then I can connect, but the client stucks again.

On the server /var/log/messages is blown up by lot of this messages:
Nov 17 09:18:32 lmesim138 /usr/bin/x2gosuspend-session: session with ID 
lmegast5-50-1507636342_stDGNOME_dp32 has been suspended successfully
Nov 17 09:18:32 lmesim138 /usr/bin/x2gosuspend-session: session with ID 
lmegast5-50-1507636342_stDGNOME_dp32 has been suspended successfully
Nov 17 09:18:42 lmesim138 /usr/bin/x2gosuspend-session: session with ID 
lmegast5-50-1507636342_stDGNOME_dp32 has been suspended successfully

This message is added even if no client is trying to connect or disconnect.

Taking a look on the open files (lsof) shows that the session log file 
in /tmp has been deleted meanwhile:
/tmp/.x2go-lmegast5/C-lmegast5-50-1507636342_stDGNOME_dp32/session.log 
(deleted)
(background: "old" files in /tmp are deleted automatically after 3 weeks 
of beeing not used/touched)

I assume thats the reason why I cannot connect to the session again.

Do you have an idea how I might make the session working again or 
overcome the problem in general?
(I sometimes have simulations running for a longer time and the 
result/evaluation will be done and shown within this session)

Best regards,
Markus
