maximum number of domains??

[joe mcguckin <joe%via.net@localhost>]

Are there any limits to the number of domains you can put on a server?  
I have a dual quad core opteron box that I was
trying to stress test xen on. I created 50 domains, and according to  
xm top, they're running and consuming cpu seconds.
But, I cannot login to the console of the domains after the 37'th  
one... I get the following message:

xenconsole: Could not read tty from store: No such file or directory
