Hi Everyone ....
I need some help. With my mdrun command I am getting this following error  .

Program mdrun, VERSION 4.6.5
Source code file:
/home/itlab/Documents/gromacs/gromacs-4.6.5/src/mdlib/domdec_con.c, line:

Fatal error:
DD cell 0 0 1 could only obtain 1 of the 2 atoms that are connected via
constraints from the neighboring cells. This probably means your constraint
lengths are too long compared to the domain decomposition cell size.
Decrease the number of domain decomposition grid cells or lincs-order.
