DWR call throws "Failed to read input" in IE8, appearing too frequent

Question

This issue occurs in IE8 only, On browser it throws http 502 error ,while in apache it throws http 103 & my application breaks due to this error

After adding sysout in dwr jar i got the following logs:

Inside marshallException
Exiting from marshallException
Returning from PlainCallHandler

I found few solution for the above issue :

1)Increase keepAliveTimout in apache

2)Change the way of reading input in ParseUtil class of dwr jar from

BufferedReader in = new BufferedReader(new InputStreamReader(req.getInputStream()));

to

BufferedReader in = req.getReader();

But issue is still reproducible in IE8

I also tried to give alert message "Internal Server Error. Please Try Again" when this exception occur but alert is not coming. I have done changes in dwr-engine.js for showing alert message

when does this exception comes.. what are u actually trying to actually achieve out of this.. plz elaborate ur issue — Garry, May 02 '13 at 15:55

Please also give more details about what you are doing to trigger this error. What JavaScript are you executing in the browser when this happens? — Old Pro, May 12 '13 at 19:35
