[X2Go-User] Disable session suspension

Yes. That's actually in place and working very well. This environment can't tolerate users having an application open and sitting idle (not suspended) on their computer screens without time limits.

I appreciate your help. I understand some of these request may seem unorthodox, but I guarantee you they are driven by legitimate business needs and constraints. 

Thanks,
Ivan.

Hmm, weren't your last words "I can easily combine the information from x2golistsessions_root and the load balancer to determine if sessions are executing work in the background and thus avoid killing them."?

So now you're planning to kill them regardless?
Parse the output of x2golistsessions_root in a cronjob, select those that have the suspended flag, and issue x2goterminate-session on their session id (as root).
Of course, one small network glitch and they're gone before the user has a chance to reconnect, so you might want to check the timestamp in the x2golistsessions_root output, and only terminate those that are suspended for longer than n minutes.

Untested and nasty hack that could/should work without a cronjob:
Create a Symlink in "/usr/local/bin/" named "x2gosuspend-session" and have it point at "/usr/bin/x2goterminate-session".

Of course, the sane approach would be using a load balancer that can actually handle reconnects.  Ours does and is called X2Go Session Broker. ;-)
