That generally means you don't have enough (or perhaps even any) swap space.

What does "free" show?

$ free
             total       used       free     shared    buffers     cached
Mem:       1025972     988224      37748          0          0     249564
-/+ buffers/cache:     738660     287312
Swap:      3004112     129140    2874972

If Mem/Used is less than Swap/Free, you have a problem.   If you don't have
_any_ swap, try: "sudo swapon -a".
