that generally means that your trajectory is corrupted. Did you check
the trajectory (gmxcheck -f traj.XXX).
If gmxcheck give the same message, I am afraid the trajectory is lost.
You can recover the good segment of the trajectory with:
trjconv -f traj.xtc -e XXX -o traj-cut.xtc.
XXX is the time before the magic number problem shows up.
