[Paraview] Paraview 3.6.2 / Open MPI 1.4.1: Server Connection Closed! / Server failed to gather information./cslog

[Utkarsh Ayachit]

I am not sure why that could be the case. The only thing that happens
on setting cslog is that each the server process starts writing out an
output log file. Also I am not sure why mpi would hang on attaching a
debugger. Try debugging by just running 2 processes. Is it possible
you have a  broken MPI?
