[Paraview] Experience with hanging OpenMPI

[pat marion]

Hi, just thought I'd share this in case someone else runs into the same
issue-

After upgrading my computer to dual quad-core intel xeons, and installing
Ubuntu Karmic (9.10), pvserver with mpi would hang after a few renders.  It
turns out it was this bug:

https://bugs.launchpad.net/ubuntu/+source/openmpi/+bug/504659
https://svn.open-mpi.org/trac/ompi/ticket/2043

I removed the openmpi-bin and libopenmpi-dev packages and installed
libmpich2-dev and mpich2.  Now everything is stable!
