Subject: [Boost-users] [interprocess] hanging when open_or_create a mapped file

hello, everyone:

    I¡¯m a newbie to boost::interprocess, It¡¯s really a cool library,
so I try to write a simple program to test mapped file, it¡¯s really

#include <boost/interprocess/managed_mapped_file.hpp>
using namespace boost::interprocess;

int main()
    managed_mapped_file mfile(open_or_create,
                                1024); //hanging here.
    return 0;

but it¡¯s hanging on the creation of mapped file, I test it both on
ubuntu 11.05(in virtualbox) and openSuse, the same problem remain.
I¡¯m sure the file exists, and I traced down the source code, it seems
the program stuck in a while loop in function priv_open_or_create(...).

except that, if I set the third argument of constructor from 1024 to 1,
it¡¯s even throw a exception( not good).

any seggestion is appreciated!!!
