There are OOMs observed at 6D, Vincent mentioned things froze and then after sometime had to restart the console (x06da-cons-02), then GUI dead and free up the console.

Simon checked and provided the following logs:
Jul 06 16:35:20 x06da-cons-02.psi.ch kernel: ZMQbg/IO/0 invoked oom-killer: gfp_mask=0x140cca(GFP_HIGHUSER_MOVABLE|__GFP_COMP), order=0, oom_score_adj=200

and gave some messages right before the crash:

Not sure whether the bug is in the GUI/DAQ/JFJoch, need to look into it.
