My computer stuck at turning on dynamic load balancing

GROMACS version:5.1
GROMACS modification: no
Hi. I’m trying to run mdsimulation on Super-Computer but when i run this command…
gmx mdrun -deffnm nvt

It turns on dynamic load balancing but stuck there. After 20 minutes server close the connection. As shown in attached pictures.
I’ve been trying this but no success.

Ask your system administrator; this message comes from the OS and has nothing to do with GROMACS. Someone is rebooting or shutting down the node that you’re using.
