It is possible that the system is unstable/exploding due atoms being too close to each other in the initial system.

Subject: [gmx-users] fatal error

Hi all
I am trying to relax the density of an alcohol system that I have just set up, but after a certain period of time I get the following error

Fatal error:
The X-size of the box (6.800588) times the triclinic skew factor
(1.000000) is smaller than the number of DD cells (4) times the smallest allowed cell size (1.700000)

I have never had this error before when I ran simulations on much more processors for the alkane analogues of the alcohol.

What is the source of this error ?
