Yeah I'm trying to simulate a CMP system with up to 64 cores and 256 thread
contexts in total. And I may create a batch of 8 m5 instances on the same
machine. So there may be 2048 thread contexts simulated. My system worked
fine with M5v2beta3. for beta 4, I'm not sure if I can open so many files
but I'll try. 

Thanks anyway! And let me know when you remember if there is a magic switch
:)

Are you simulating many systems or many processors? M5 needs a certain  
number of open files (just like any other process). You might want to  
try to increase the number of open files allowed by using ulimit (or  
something similar depending on what OS you're using).
