Fatal error during md run

GROMACS version:
GROMACS modification: Yes/No
Here post your question
Hi,
I am getting the fatal error during md run:
An atom moved too far between two domain decomposition steps
This usually means that your system is not well equilibrated.
I did both nvt and npt equlibration run for 1ns each.

Thank You,
Yours sincerely,

Dear sir,
During equilibration I got some warnings. Are they are responsible for the fatal error?


Thank You
Yours sincerely,
