Please go back and read my first reply again.  

With the extra information (still minimal... please post doTheAction()!)
you've provided, I'm now more convinced that my first guess was correct.
You very likely have a code-reentrancy problem, possibly because you're
using a global variable (?), which is causing the problem.

The above code is certainly starting two threads.  The issue is how
does the first thread hear about "hostname2" instead of "hostname1".
The only likely answer is that you do not have thread-safe code.
Please post doTheAction() if you can't find the problem yourself.
Without it, we're stuck.
