Dear all, I use LAMMPS on the cluster server. The simulation can proceed normally, but the following error will appear at the end ("* Error in `lmp_mpi’: free(): invalid size: 0x00000000021be970 *"). I don’t know what the reason is. It seems that it is the server problem rather than the lammps problem. Has anyone encountered it?

This is due to a bug in the code. However, since you are using an outdated LAMMPS version (>2 1/2 years old), none of the LAMMPS developers will investigate unless you can reproduce it with the current version of LAMMPS. Chances are, that it is already fixed (unless you have a modified version of LAMMPS, then the bug may be in the modifications).
Thanks, I will try the latest version.
