well... so that's just a client disconnect on GET. You should be able to duplicate it by starting a GET request for a large file and then killing the client before the transfer finishes. The proxy has some code that manages closing and timing out the client and backend connections to prevent tcp buffer leak - there's some warning/error log lines that pop up when this happens.

Maybe those specific log lines to be more specific or less noisy?
