Hi Goodwin,
There is a bug in vtkSocket::Receive, where the error condition is not
tested for in return from recv socket call on *nix systems. It may or
may not be the source of/related to the issue that you are having but
it's certainly could cause ParaView to hang silently. Sorry that I
didn't submit the patch sooner, am way behind on the "new" git work
flow. I've filed the bug report
http://www.paraview.org/Bug/view.php?id=12955, hope it can make it into
3.14.

Following up on this.
I built a debug 32bit version of ParaView 3.14.0-RC2 client on Win7
It hangs on connecting to a remote server (linux 64bit) too.
Here's the backtrace:

Utkarsh & John,
Thanks for the tips! I'll investigate further.
FWIW, this is how I checked out the source code:
$ git checkout -b release-3.12.0 tags/v3.12.0
$ git submodule update
Initially, I hadn't updated the submodule and did hit the version
incompatibility thing.

I've had the hanging problem a lot. Last time I found that my VTK ref
was not quite the same as the ref that the paraview repo was asking
for. When I corrected it, all was well, but it seems very sensitive to
changes which (in my opinion) shouldn't have made any difference.
Make sure git submodule update/status doesn't show any grotesque
incompatibilities. It might help ...

Subject: Re: [Paraview] ParaView 3.12.0 hanging
The server is expected to complain once the client is killed. The real
issue is the hanging part. Are these debug builds? Is it possible to
produce a backtrace?

Hi All,
We upgraded pvserver from 3.10 to 3.12
Now when the client (Win7 64bit) connects remotely to the pvserver
(linux 64it), it hangs.
When you kill the client, the server complains:

Client connected.
