Hello,
This problem seems to be quite common, but I still cannot solve it.
I am getting following run for mdrun
starting mdrun 'System'
100 steps, 0.0 ps.
step 0Segmentation fault: 11
If I look at md.log (full file at the end)

My temperature is insanely hight. I wouldn't normally panic for the T to be
extremel high at the first step (correct?). I cannot get more insights on my
the error occurs. I could always blame it on poor minimisation, but systems
not inadequate at the start.
I am using 9-6 LJ and tabulated bonded & angle potentials.
I would be very happy to hear any advises,
Thank you
