Hi all,
      I am using LAMMPS Jan-2011 version for my work.
After some early lags, i started using LAMMPS successfully.
But now,i found a the following message at the end of my simulation.
However, the simulations has run perfectly without any problem.
Could you let me know what does these messages represent.
Will it affect the simulation running properly

Hi all,

Your binary crashes while writing a restart.

Will it affect the simulation running properly

Yes, you cannot write restarts.

You should upgrade to the latest version. Your version is outdated.

Hi,
  Thanks for the information. I will update the version.
But, the present binary was working fine even for writing the restart file till last week.
Is it possible for the binary to crash suddenly like the way it is happening now.
What could be the possible reasons for it.

Thanks in advance

sorry, i broke my crystal ball a long time ago and now my
guess is as good as yours. segmentation faults can happen
for a variety of reasons. it can be as simple as having changes
in the default stack size limits or as nasty as a faulty disk
or memory module somewhere.
