Hi Bart,<br><br>Any chance you can attach with a debugger to one of the nodes that crash? It is hard to tell what is wrong from the errors you posted. We have definitely run ParaView with OpenMPI with 4 core and more. Also, what do you mean by "simple VTK file"? Small file? Big file?<br>

Hi all,<br>
<br>
I've been trying to run pvserver using 8 processes. It accepts the connection,<br>
but when loading a simple VTK file it crashes. Exactly the same line with -np 4<br>
does work. The problem appears on both paraview SVN and 3.6.2. The machine has<br>
8 cores, below is the full command and output:<br>
<br>
mpirun -np 8 /share/apps/paraview-3.6.2/bin/pvserver --use-offscreen-rendering<br>
-rc -ch=10.67.81.131<br>

mpirun noticed that job rank 0 with PID 3569 on node <a href="http://mach.intra.rma.ac.be" target="_blank">mach.intra.rma.ac.be</a><br>
exited on signal 11 (Segmentation fault).<br>
7 additional processes aborted (not shown)<br>
<br>
Anyone have an idea what may be causing this?<br>
<br>
Cheers,<br>
<br>
Bart<br>
