Hi Managers,
after a week in holidays I have found a crash in DPW 600au. It seem be
an hardware error during IO operation on a disk but the disk was /
....
The crash-data was:
panic_string:"k_mem_fault: IO error during kernel pagein"
msg_bufc = "Alpha boot: available memory from 0xdee000 to 0xfffe000

What you think about?...
is it really an Hardware ERROR :-( ?
Have I to call the Digital/Compaq Hardware support :-( ?
>From Fri Jul 30 there aren't more hard errors,
but there is an "excessive page-in activity" on the system....
Could be a relation between the crash and the page-in activity?
Any and all help is greatly appreciated
