[gmx-users] Segmentation fault in some windows of umbrella sampling

[gozde ergin]

Dear users,

I am doing umbrella sampling and using gromacs 4.6.
I followed the Justin tutorial and generated 200 configurations on reaction
coordinate.
I faced segmentation fault error for 34 configurations (windows) but 166 of
them run without any error.
I thought maybe systems were not equilibrated enough so I run energy
minimization step by using double precision, lower energy step and maximum
force however I still get the same error.

Do you have any idea about the reason?

Any help will be appreciated.
