Cause
These exceptions are caused when a user's browser terminates a connection, for whatever reason. They typically happen if a user shuts a browser tab while it is loading, or navigates away from the current page before the page itself is fully loaded or one of the items on the page (e.g. the avatar image) has finished being sent.
Resolution
These exceptions are totally harmless and can be safely ignored. Other than adding some noise to the Fisheye logs, they do not indicate any problems with the application itself.
