I have installed CentOS 5.5 (2.6.18-194.17.1.el5PAE) on a number of Acer Veriton X498G desktop computers. They seem to randomly hang when nobody is logged in at the console, i.e. I notice a hanged computer but have not heard complaints about computers hanging while a user was at the keyboard.
The symptoms are: Blank screen. Power LED on. Network LED blinking. No response to keyboard or mouse. No response to ping. Arp request from computer on same subnet gets "incomplete" for MAC address. Cannot ssh into computer, "no route to host" error message.
This is all consistent with a non-listening NIC and a unit in profound hibernation, if not affirmative shutdown [NIC lights will be powered on and blink by stray ARP broadcast packets moving across a lan, even on switched fabric]
Has anyone else seen similar?
as above ... I
would set up remote syslogging from the unit under test, and see exercise (through keyed ssh access) that unit under test on a scripted basis, to see if it dies off if left alone, or if other clues appear in that remote syslog
