https://issues.apache.org/bugzilla/show_bug.cgi?id=55316

            Bug ID: 55316
           Summary: Ugly error log when WS client diconnects unexpectedly
           Product: Tomcat 8
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: david_syer@hotmail.com

When a WS browser client disconnects unexpectedly (e.g. in the SNake sample if
the user just closes the browser or loads another page) you get ugle ERROR logs
in the Tomcat server.  E.g.

Presumably this is expected to be relatively normal, so I'd expect a lot less
noise (and no ERROR) in the log?

--- Comment #1 from Mark Thomas <ma...@apache.org> ---

the log level to debug.
