[lammps-users] p4_error: net_recv read: probable EOF on socket: 1

Dear, everyone

When I run the simulation with a script input file.
In the input script , run 20000 timestep first.After it is finished,
then setting up run 20000 occured error:

The error occured as follows:

I performed the parallel simulation with 4 processors.When I set one run
in the input script, it will not occured any error.

The version of the lammps is lammps-24Oct08.

I used pgCC with mpich1.2.7 on AMD machines

I will appreciate your help

Fred

Please post your input script and data file
