Apache2::RequestIO::print: (53) Software caused connection abort

Error logs are filling up with strange "File does not exist" errors and code
is trapping Apache exception:

         Apache2::RequestIO::print: (53) Software caused connection abort

These errors are repeatably caused by client breaking the connection before
page has loaded (page loads slowly because of extensive javascript).

Is Apache misconfigured? Is my code failing to handle interrupt? Guidance
greatly appreciated!
