Hello,
In fact, while coming up with a small reproducing sample, I realized
that the code is working with multiple clients if the data sent is
small. In the sample, the objects are around 1 KB, and in the case that
doesn't work, much larger objects are sent ( > 700 KB).
This tells me that something is definitely wrong in my code. Let me do a
little more investigation into this, and I will update you on what I find.
Sincerely,
-Laurent

Hello Emmanuel,
Thanks for your reply. I'm perfectly comfortable with English, so I'd
rather stick to it, in case anyone else could benefit from reading
this thread.
As far as I know, the points you mentioned previously are already
handled. The only thing I do not need to handle is the case where we
have multiple messages per incoming buffer, because the application
is built in such a way that a client always sends a single message,
and always in response to a server command.
The code I'm using is essentially an adaptation of existing code that
was using non-blocking NIO low-level APIs directly, and it was
already handling these issues, including potentialy partial length
values.
The code for this can be found there:
http://jppf-project.cvs.sourceforge.net/viewvc/jppf-project/server/src/java/org/jppf/server/mina/nodeserver/NodeMessage.java?revision=1.1&view=markup
In any case, if I were missing one of these points, it wouldn't even
be working with a single client, would it?
Not necessarily, but at this point, I would first check that the code
with a single client is correct, as you suggested :) I think that your
approach is correct.
What would help is a simple multi-threaded client injecting messages
to the server, in order to be able to reproduce the problem easily.
It's difficult to tell what's going wrong by looking at the code... :/
As per your request, I can put together a simple test that will
reproduce the issue. I just need to take some time to package it, I
hope it's OK if I send it tomorrow or the day after?
NP, I'm currently a bit busy too with some bugs to fix on another
project.
