Hi,
I've had this issue before but haven't figured it out. It still happens
once in a while - I get sessions that won't die after calling
x2goterminate. Here's one that's stuck now:

1174|asharma-62-1450478577_stRPUBLISHED_dp32|62|cx2go.uphs.upenn.edu
 <http://cx2go.uphs.upenn.edu>|R|2015-12-18T17:42:57|e016e30d1277cccb5d7360cc8760c01f|170.212.109.160|30045|30046|2015-12-18T17:43:27|asharma|247541|30047|

Furthermore, there's no process 1174 running, and the user asharma isn't
running any processes either. This user is currently having trouble
starting a new session, and I don't know if it's related to this or not.
Anyone have any suggestions? Thanks.

Is x2gocleansessions.service running?

systemctl status x2gocleansessions.service

This seems to have done the trick:

[root@cx2go ~]# systemctl status x2gocleansessions.service
x2gocleansessions.service - X2go session cleanup
   Loaded: loaded (/usr/lib/systemd/system/x2gocleansessions.service; enabled)
   Active: failed (Result: exit-code) since Mon 2015-09-14 14:53:23 EDT; 3 months 7 days ago
 Main PID: 731 (code=exited, status=255)
   CGroup: /system.slice/x2gocleansessions.service

Now x2golistsessions_root doesn't show the couple sessions that recently wouldn't terminate from x2goterminate-session. 

Thanks!
