I'm hoping someone familiar with libuv, and its use with websockets can 
help me out.  I've run into a really confusing problem...

I've implemented a http/websockets server in C++ using libuv.

I've got json successfully being sent and received in both directions 
client->server and server->client (asyncronously -- single threading 
server).  The client is a browser, either mobile or desktop.

The json messaging almost always works fine on my developer machine (recent 
MacBook Pro), BUT
on my client's much older windows laptop, running Chrome, and every once in 
a blue moon on my dev machine, the server is receiving garbage when the 
browser tries to send any largeish-chunk of json (ballpark 2 single-spaced, 
pretty-printed pages -- not really -that- large!).  Needless to say, this 
wreaks havoc on the app as it misses key messages like "Save" and such.

Why would the libuv/websockets transport work with a newer machine, but not 
with an older one?  Could network congestion be playing a part?  How could 
I work around it, if so?

Is there some limit to javascipt client sending size I need to pay 
attention to, or somehow tune? 

Should I set up a javascript chunking function and send large messages in 
parts?  I thought the transport layer was supposed to handle this, but it 
doesn't seem to be.

This has been a very difficult problem to track down, since it is only 
happening once I deliver a release.  To make things worse, I have no window 
into the app, when the client runs it remotely, since it is meant to run on 
a private wifi network.  I have been able to capture logs a couple of 
times, however, when he runs it on the live internet, but they only show 
incoming garbage.  Well, to be fair, several lines of good message, 
followed by lots of garbage -- usually the same junk character repeated 
many times.

Can anyone suggest what might be going on here, and how to approach solving 
it?

Thank you for any thoughts you pass along.
