Yeah I've gotten a similar notification: "During the night of 30.06.2012 to 01.07.2012 our internal monitoring systems registered an increase in the level of IT power usage by approximately one megawatt. The reason for this huge surge is the additional switched leap second which can lead to permanent CPU load on Linux servers." Interesting times when we need to start writing unit-tests which asserts power-consumption levels! I'm still searching for more detail, considering how much of my stuff runs one form of Linux or another (router, NAS, phone, HD recorder etc.) it would be interesting to get an idea of just how widespread this issue is. -- You received this message because you are subscribed to the Google Groups "Java Posse" group.
