This could be a system-dependant error. I can't tell you how to make the code go away, but here's how you start: identify exactly what is causing it. Strip that puppy to a minimal test case. What's the fewest lines code you can use to recreate the error?

Also, you said you don't get the problem when you run it for 2 hosts, but you do for 20. What about 4 hosts? 5? Once you've nailed down the exact conditions under which the problem occurs, you may be able to find a way to avoid those conditions.
