I updated the procps package to 3.2.8-2. It adds a Cygwin-specific patch which should avoid the "Unknown HZ value!" message once and for all. For details, see http://cygwin.com/ml/cygwin/2013-11/msg00383.html
Have fun, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Project Co-Leader cygwin AT cygwin DOT com Red Hat
