multisphere and restart command cause abortion

Hi all,

in version 3.3.0 of LIGGGHTS®-PUBLIC a serial multisphere method is included. I played around with the provided example and modified one of my spherical simulations for the use of multispheres, what worked very well. The simulation is divided in different steps, at the end of step 1 a restart file is written, which is read at the beginning of step 2, but the read_write cause on abortion of the script which seems to be related to MPI. For verification I added a write_restart and read_restart to to original example multisphere_stone_restitution. The test case multisphere_restart is provided in the zip-archive.
Is the error caused as a consequence of the limitation to serial?

Regards,
Paul
