[AMBER] Asterisks in the restart file

Hi all,

I came across a problem with my MD recently. The system is a membrane protein containing about 70,000 atoms and was simulated with AMBER11. The following is the input file of production phase.

production hSGLT2_dpp
  cut=10.0, ntb=2, ntp=2, taup=2.0,
  ntpr=1000, ntwx=1000,
  ntt=3, gamma_ln=2.0,

When the job went to 38ns, some asterisks appear in the restart file. That leads to the impossibility of restarting the job. Now the only thing I can do is to avoid breaking the calculation. I copied some of the data in the rst file.

 59.7272199************ 137.8027357 -59.5537208************ 138.0484368
 60.4061406************ 138.4130880-156.4547856 88.0830801 142.243969
My question is:
Why did this problem arise and how should I fix it?

Many thanks!
