I just noticed that one of our Tru64 systems had rebooted itself a couple
of days ago. I found the following the /var/adm/messages :


Apr 21 21:12:20 cams1 vmunix:
Apr 21 21:12:20 cams1 vmunix: trap: invalid memory read access from kernel
mode
Apr 21 21:12:20 cams1 vmunix:

Apr 21 21:12:20 cams1 vmunix: sp contents at time of fault:

Apr 21 21:12:20 cams1 vmunix:
Apr 21 21:12:20 cams1 vmunix: panic (cpu 0): kernel memory fault
Apr 21 21:12:20 cams1 vmunix: syncing disks... done


Does anyone know what the cause of the above is? This system has been
running fine for years without problems. Does this indicate a hardware
problem, such as with the system's memory or CPU ?


Thanks,
