What exactly do you mean by "killed"?
How do you tell a thread that it should end?

What do you mean by "it works as expected" ?

What exactly happens in which order?
Starting the program & Creating the threads then running for some minutes?

or

Starting the program then waiting then creating some threads?

or

Starting & creating then waiting the stopping (the threads) later 
creating another set of threads ?

Why do you think it shouldn't?

Usually you will get better help if you try to strip down your code, 
until you find a small enough example that has the same behaviour than 
yours. Even if you would post your code I suspect you wouldn't found 
many here which will help to debug it for free under these circumstances.

Please try again to restate your question.
And please also specify some of the more common things too:
Used boost version, platform, compiler, ....

Thank you,
