[lammps-users] Restart the simulation with "p4_error: interrupt SIGx"

Dear, everyone

when I restarted the simulation with a restart-file,
the error of “p4_error: interrupt SIGx” occured.
The error was always one of the following three errors.
I also found that these errors disappeared when the nodes used were less than 3. However,I can successfully performed the parallel simulation with a input-data file (with any number of nodes).

The version of the lammps is lammps-16Jul08.

I used g++ with mpich1.2.6 on intel Quad-core xeon 5405.
I appreciate your help.

Three errors as follows.

Can you post a simple (as possible) example that reproduces
the problem. I.e. one input script that creates the restart file,
the restart file, and a 2nd input script that reads the restart
file and crashes?

Are you using the most current version of LAMMPS?


This was a bug with reading restart files that contained
hybrid bond, angle, etc potentials. Posted a 20Aug08
patch that should fix it.
