Client did not send n bytes as expected

Question

We get this error:

[#|2009-08-12T11:38:31.803-0700|SEVERE|sun-appserver9.1|javax.enterprise.system.container.web|_ThreadID=16;_ThreadName=httpSSLWorkerThread-38080-3;_RequestID=8b3571bb-3c36-43f1-9e38-6947ca376436;|WebModule[]Exception while dispatching incoming RPC call
javax.servlet.ServletException: Client did not send 142 bytes as expected

    at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java:77)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:738)

very rarely and it is not reproducible. I have seen posts earlier but none of them justify the reason for it.

Appreciate if I can get some information:

1. Is it with some version of GWT or related software, will upgrading help?
2. How often you get this error?
3. Any more workaround?

Environment: Client: ie 6 Server: GlassFish 2, GWT 1.5.3, Java 5

It seems it's not related to GWT: http://code.google.com/p/google-web-toolkit/issues/detail?id=3155. There's also someone there in the comments offering (private) help with this issue.
