Hum, the client is crashing? Has this been happening all the time?

Looks like it's crashing while executing x2goterminate-session. I assume you
clicked the terminate button in the left section of X2Go Client while the
session was running?

I assume you used the OS X 10.10 package? If I map the address given in the
crash report, the crash seems to be happening after calling the new operator and
before calling the constructor for a new object. Normally something like that is
impossible - unless the application managed to corrupt the heap, stack or the
system's memory is faulty.

Still, I'd leave this aside for now, since this issue is only triggered by
clicking the terminate button. The more pressing issue is that the session is
not starting correctly at all, right?

The server log is a bit convoluted - there are two sessions;
localguy-142-1509294346_stDXFCE_dp32 which seemingly is getting suspended and
kudyba-144-1509312107_stDXFCE_dp32, for which the agent gets started, but
seemingly terminates later on and X2Go Client checks the exit status. It doesn't
match the 143-DISPLAY-number session that has been started in the client log,
but I guess it's just because you ran separate attempts to get these log files.

Something isn't right - did the process crash after this line?

Did nothing happen after spawning nxproxy, other than its startup message? Was
it just hanging there for a prolonged amount of time, so that you hit the
terminate button at some point?


Let's get this straight, though, you have two server machines, with one (the
FC26 Server machine) able to spawn X2Go sessions and the other one (FC26
Workstation) not able to spawn X2Go sessions?
