Could I be forgetting to do something on the client side? Is this a
problem with Tomcat? Could it be a problem with my code (unlikely as
that is... :-\ )? Any hints would be appreciated! Thanks!

It is a disconnect - something fails between the browser->apache-
>tomcat. The class throwing exception is basically an inputstream
wrapper in tomcat to parse HTTP requests. Are you using something like
Scriptaculous or any standard Ajax framework for the communication, or
have you written something of your own? If latter, you might want to
try using Scriptaculous/Prototype and see if the error goes away.

Thanks for the response. I have a webapp which throws a similar
exception which is pasted below. I am using Tomcat 5.5.23.

When exactly is this "socket read failed" thrown ? I have even tried
changing the maxPostSize to a maximum value, but in vain.
This exception seems to be thrown for each of the post request.
Please help me with some pointers to overcome this issue.
Thanks,
Alex
I have two servers, one running with the native library and one
without it. The one with the native library still has this exception
thrown (even after upgrading to Tomcat 6). I have not observed this
issue with the server running without the native library. That's my
best guess.
Jeff
P.S. - I just assumed you were using Windows. I don't think the
Tomcat native library is supplied for any other OS. If you're not
using Windows, then you can probably ignore everything I just said.
