Please be more specific. Explain step by step what you are doing and what failes.
Are you saying that when you want to start a forth SSH session to the guest, it fails and the Guest crashes?

well, i have a local LAN with 16 pc's . 8 of them have windows xp and 8 red hat. I want to make a platform , with all my pc's , doin mpi using all my pc's with both operating systems, so i used on windows xp virtualbox with red hat, and load on guest OS mpich.i manage connect all pc's with ssh , using port forwording as it says on virtualbox manual. I used NAT connection to virtualbox.
Starting mpich with 2 pc's , one red hat and one windows xp(forwording on virualbox), and it works perfect, try it with one red hat and 2 windows and again works perfect , but when i try with 3< windows xp pc's dont get eny result , no replays.

i dont know what am i doing wrong , or virtual box not support more pc's.

I don't have any experience with MPI or similar setup. Sorry, but I can't help you any further.
