A few more questions:

1) What version(s) of libzmq are you using, both in C# and C?

2) In the C# code, why are you using pinned GCHandles and Marshal.Copy to
convert your hash code to a byte array (lines 34-39)? This isn't
necessarily related to your problem, but you'd be much better off using
Buffer.BlockCopy (
http://msdn.microsoft.com/en-us/library/system.buffer.blockcopy.aspx).
Pinned GCHandles are evil for a lot of reasons and, as far as I can tell,
don't need to be used in this situation.

3) In C#, are you using non-blocking Sends on purpose? This shouldn't make
a difference, but you don't have a retry mechanism for failed sends, so you
should probably be using blocking sends.

These may not be related to your problem, but it's a start...
