Summary0011592: pvrenderserver segfault with more than 2 servers
DescriptionI have the following setup: 1 node with 12 cores and 4 GPU (tesla C2050). I
want to start 8 dataserver and 4 renderserver on this host (paraview 3.8.1,
fedora-12 x86_64, openmpi 1.4.3, nvidia drivers)

It works if i start only 2 renderserver; however with 3 or 4 renderservers,
it fails (segfault)

Logs:

Listen on port: 22221
RenderServer: Waiting for client...
Client connected.
Connect: id :1 host: localhost Port:52065
Connect: id :2 host: localhost Port:52975
Connect: id :3 host: localhost Port:29181760
Connect: id :0 host: localhost Port:53883

a port number > 65535 is a bug
Steps To Reproducethe renderserver segfault as soon as the client tries to connect to the servers.

commit d3f7da173de4186dca8e6a0409145a75f210e5c5
Author: Utkarsh Ayachit <utkarsh.ayachit@kitware.com>

    Fixed BUG 0011592. Information was added up incorrectly.
    
    This was resulting in information from child processes being lost and hence we
    ended up with invalid port numbers when number of processes is > 2. This bug
    must have surfaced when we switched to using the "tree" for gather information.
