ROS node crashes and log file doesn't exist

edit

My Ros nod crashes and I get told the following:

[time_criterion-3] process has died [pid 21050, exit code -11, cmd /home/neuroreact/catkin_ws/devel/lib/neuromorphic_stereo/time_criterion __name:=time_criterion __log:=/home/neuroreact/.ros/log/a959c3ea-0d19-11ea-aca0-e470b83fbf06/time_criterion-3.log].
log file: /home/neuroreact/.ros/log/a959c3ea-0d19-11ea-aca0-e470b83fbf06/time_criterion-3*.log

So I did

cd /home/neuroreact/.ros/log/a959c3ea-0d19-11ea-aca0-e470b83fbf06
ls

and I get this output:

-rw-rw-r-- 1 neuroreact neuroreact 383037 Nov 22 12:17 event_publisher-2-stdout.log
-rw-rw-r-- 1 neuroreact neuroreact  25569 Nov 22 12:17 master.log
-rw-rw-r-- 1 neuroreact neuroreact  60716 Nov 22 12:17 roslaunch-ids-qoros-21021.log
-rw-rw-r-- 1 neuroreact neuroreact    156 Nov 22 12:17 rosout-1-stdout.log
-rw-rw-r-- 1 neuroreact neuroreact    269 Nov 22 12:17 rosout.log

So where is the log file of my time_criterion-node?
Some google search led me to this but the solution here of using stdbuf -o L roslaunch <launchfile> didn't change anything.
Any other suggestions?
