[Paraview] Can't connect any more in pv3

[John Biddiscombe]

I've been using pv3 all day long to connect using reverse connection to 
an mpi spawned server, then I though I'd save myself some fiddling, by 
entering the command into the configuration dialog for the connection so 
that paraview client would
ssh machineX mpirun -hostfile /users/biddisco/build/pv3/bin/pvserver -rc 
--client-host=machineA
etc etc
It worked ok the first time, then I fiddled some more and now despite 
deleting all servers, removing the paraview .config file, reentering 
servers the way I've been doing for weeks, I cannot get anything except 
this message from the client


ERROR: In 
/users/biddisco/code/ParaView3/Servers/Common/vtkProcessModuleConnectionManager.cxx, 
line 180
vtkProcessModuleConnectionManager (0x4f69290): Failed to set up server 
socket.

ERROR: In 
/users/biddisco/code/ParaView3/Servers/Common/vtkProcessModuleConnectionManager.cxx, 
line 200
vtkProcessModuleConnectionManager (0x4f69290): Invalid ServerSocket id: -1


I didn't do anything else to the system except change servers - then 
delete them and re-enter them. Reverse connection just fils immediately 
now, whereas it used to open up the dialog and wait for a connection...

What do the two lines of error above really tell me, and how can I make 
them go away. Unless someone has secretly reconfigured the network 
whilst I wasn't looking, I cannot imagine why these errors suddenly 
appeared.

Clues?

thanks

JB
