chris, The hardware has same identical spec with others, and hosting for internet service independent, and the model of hardware is very popular and proven to be used in internet service, of course, it still needs check to ensure its quality. I will ask hardware team for help to check that points

elopers. I get the feeling that Sun has about 3 experts and 3 interns working on the JVM lately, and no one else. The last time I filed a bug report with them (which, coincidently, was a JVM crash issue) with a test case that made it trivial to reproduce, it was 2 months before they would even
