Scott, I notice that in com.caucho.hessian.server.HessianSkeleton there are lots of out.close() but no out.flush(). Could unflushed buffers be what is causing this? At least then difference in output size could explain why it works sometimes on the production server and always in test environment.

(There is a 200 status in the server log regardless of the result on the client and the size of the response is about 200 kB)

I was able to see the error myself today. It occurs within 3 seconds from the Hessian call, so I doubt this is some kind of timeout issue.

I can't see any traces of this on the server side.

Any other ideas???
Should I add some debugging code somewhere?

Nope - standalone Resin.
It would be a different issue. This looks like a timeout issue, while the previous one was a protocol problem.

On the server side, are you seeing any timeout of that connection? Or does changing the socket-timeout avoid the issue?

If u'r using apache or other web server backended by resin instead of
running resin standalone, I think the 1202 snapshot should fix this
issue.

We are seeing a lot of "Connection reset" with Hessian since the upgrade
of our production environment to 4.0.2 (both client and server). Would
this be related to the problems already reported against 4.0.2 and thus
fixed in the snapshot?
