mpirun and write_data conflict

when I use the "mpirun -np 2 lm_openmpi < in.script" the following error occur, but when use "lm_openmpi < in.script", everything is OK.

write_data restartfile
System init for write_data ...
[mehdi-System-Product-Name:2527] *** An error occurred in MPI_Allreduce
[mehdi-System-Product-Name:2527] *** on communicator MPI_COMM_WORLD
[mehdi-System-Product-Name:2527] *** MPI_ERR_TRUNCATE: message truncated
[mehdi-System-Product-Name:2527] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)

fixed it - will be in a patch later today …
