Hi Jens,
Your pvserver is probably waiting on an MPI_Recv and your MPI
implementation is spinning.
You will note that process 0 probably isn't doing this, as the other
nodes are waiting on process 0 to send.
I have searched this problem all the way to the MPI developers as
it's easy to replicate without paraview and the MPI guys assure me
the alternatives are worse.

Hi,
if I run "mpirun -np 4 ./pvserver" on our cluster-node and connect
from
my client, this pvserver always shows 100% cpu usage - even if I do
nothing at the client.
Seems to me as if there is a loop waiting for the client to ask for
action - but this loop is calling no wait/sleep function.
Greetings
Jens
