Hi, I have been running a daily test of the Boost release branch for a long time. It normally takes an hour or so. However, two days ago (rev 76868), the build time shot up to over 9 hours. The same thing happened for testing the Boost trunk branch. Others on the boost-test list have experienced the same and Jurgen Hunold pointed out that all the MPI tests are failing. According to http://www.boost.org/development/tests/trunk/developer/mpi.html this is true for about half the tester machines. Should probably be fixed before 1.49 is released! -Steve
