There is no such artificial limit on the boost side.
boost::thread_resource_error is always thrown, if the
corresponding OS cannot fulfill the corresponding
native request, e.g. if on Windows _beginthreadex fails or
if on a pthread environment pthread_create fails.

The most reasonable assumption is, that your OS cannot
provide these 400 threads at the point where you try to get them.
