Felix Meschberger commented on SLING-1815:
------------------------------------------

Can also be reproduced on Linux using Firefox or Chrome: Accessing a movie 
causes the browser to request the file and abort the request once it decides to 
have a plugin handle the request, which places a new request.

> Improve error handling of "broken pipe" socket exceptions

> If the client (browser) kills the socket connection mid-request, one gets 
> broken pipe exception stack traces, exactly three of them (see attachment). 
> The problem is that the error handling doesn't work on them, as the response 
> is already written, and you always get three stacktraces:
> 1) original exception log
> Uncaught Throwable java.net.SocketException: Broken pipe
> 2) error handling fails due to response already transmitted
> Calling the error handler resulted in an error 
> java.lang.IllegalStateException: OutputStream already retrieved
> 3) error handling logs original exception again
> Original error class java.net.SocketException java.net.SocketException: 
> Broken pipe
> A single warn "broken pipe" would probably be enough (it's not a server 
> fault).
