do you have iwrap=1? imaging will solve the problem.
start from the last good restart and rerun. if that loses
too much data, you could try using ptraj to convert the final frame
of the trajectory to a restart format (but you will lose precision
and also not have velocities).
check the archives for iwrap, there is lots of detailed discussion.
