[chitrala kumaraswamynaidu]

I have run the following command on the Cluster server  and I got the
following error. Can anyone Please help me why I am facing this error.

gmx mdrun -deffnm nvt_2 -v

Reading file nvt_2.tpr, VERSION 5.0.4 (single precision)
Changing nstlist from 10 to 25, rlist from 1.4 to 1.433


Will use 108 particle-particle and 12 PME only ranks
This is a guess, check the performance at the end of the log file
Using 120 MPI threads
Using 1 OpenMP thread per tMPI thread
starting mdrun 'Protein in water'
50000 steps,    100.0 ps.

Program gmx, VERSION 5.0.4
Source code file: /share/apps/src/gromacs-5.0.4/src/gromacs/mdlib/pme.c,
line:

Fatal error:
2 particles communicated to PME rank 4 are more than 2/3 times the cut-off
out of the domain decomposition cell of their charge group in dimension x.
This usually means that your system is not well equilibrated.
