Hi, All,

I tested two sample applications on Windows 2003 Server, one use MPI_Comm_accept and other use MPI_Comm_connect,
when run into MPI_Comm_accept or MPI_Comm_connect, the application use 100% one cpu core.  Is it a bug or some wrong?

I tested with three version including Version 1.4 (stable), Version 1.5 (prerelease) and trunk 23706 version.

...
MPI_Open_port(MPI_INFO_NULL, port);
MPI_Comm_accept( port, MPI_INFO_NULL, 0, MPI_COMM_WORLD,    &client );
...

...
MPI_Comm_connect( port, MPI_INFO_NULL, 0, MPI_COMM_WORLD,    &server );
...

thanks a lot.

lyb
