[gmx-users] segmentation fault in md

[Rui Li]

all users,

When I ran
mdrun -v -s enz_pr.tpr -o enz_pr.trr -c enz_b4md.pdb -g pr.log -e pr.edr >& pr.job
&

It stopped and prompted "segmentation fault " after about 10 second

and in the end of pr.job, it prompt 
"step 20, will finish at Tue Sep 11 22:38:22 2007
Wrote pdb files with previous and current coordinates"

what's wrong with it?
