handling MUTEX ?!

hi,

I uses a mutex to synchronise 9 processors nios II, sach a way that all processors starts execute their programs at the same time.

for that, I try implement a program that can handle mutex according to my needs.

i can't do this because the system not responding. I try implement 5 processors and i have the same problem?

but with 4 processors it work well !!!!

i can't understand where is the problem?

does the mutex that it can't support a large number of processors, or it is anothers limit that i don't know??

help me to resolve this problem and give me advice how can i implement my architecture.

thks for all members
