POSIX says: "The last data modification and last file status change timestamps of a file that is mapped with MAP_SHARED and PROT_WRITE shall be marked for update at some point in the interval between a write reference to the mapped region and the next call to msync() with MS_ASYNC or MS_SYNC for that portion of the file by any process." When I do a msync with MS_ASYNC it works as expected and it should not block the process (I did not test the latter). So it was a usage issue. Sorry for the noise... Carsten
