We have an older Xserve G4 (OS X Server 10.4.11) that freezes randomly. It will be fine for days and then will stop accepting VNC connections and does not respond to Keyboard/Mouse inputs locally. I can tell when this has happened without even trying to connect however, as the blue lights on the front are all on when this happens. Do these lights indicate an overload? I have the system set to automatically reboot when it detects a system freeze, but I have to reboot manually by holding down the power button and turning it back on.
Thanks for any help!
