Also, what sort of benchmark are you running? It's quite possible you have some sort of run away recursion or infinite loop with allocation in it and you're filling and exceeding any available amount of simulated memory. I would suggest looking at what instructions are executing after a while (--trace-flags=Exec --trace-start=<a little while before the failure>) to see if you're getting stuck in a loop. This shouldn't happen if you're running m5 right out of the box, but if you've written your own benchmark or modified something it could.
