[gmx-users] mpdboot and mpirun hangs (not crashing)

[X Rules]

Hi,

 I am trying to run my production run with mpirun and this hangs (basically stop writing any files). The processes continue to run without any output. 
 I have to kill and restart which again hangs after some time. 
 Does anyone have any problems with this?
 what I am doing is 


mpdboot -n 1 -f NODEFILE

nohup mpirun -np 12  mdrun_mpi -v -deffnm protein-prod &

what could have been going wrong here?? What could I try

Thanks,
