Standard type install nothing fancy with-mysql with-apxs.  After about 2 hours of apache seems to go ape and the load on the machine goes up to 30+.  I switched back to the last RC and it runs fine but with 4.0.0 this happens the only thing I can do is restart the web server. You can email me if you want more information or want to take a look at the box.  I haven't seen any other posts about this yet but doubt it is the box I have followed 4 through development and this is the fist issue I have had.
