MPI simulation error "word too long"
 

hello everybody
i use AVL Fire 2011 on Ubuntu 12 and when I try to start a simulation using all the CPUs (default settings) I get an error from the shell where Fire is running. After typing my password (it is needed to connect to myaccount@127.0.1.1) , it is shown:

fire_cmd@myaccount: Word too long.
Word too long.
Word too long.
MPI Application rank 0 exited before MPI_Init() with status 1
mpirun: broken pipe

Does anybody know how to solve this problem?
Thank you for your help
