Managers,

  I have a machine (Alpha 4100, DU 4.0D) that is crashing at seemingly
random intervals with no obvious reason. Does anyone know what the
following crash data could mean?

The uerf entry at the time shows a "panic (cpu 0): kernel memory fault".

trap: invalid memory read access from kernel mode

Ideas? A RAM problem?

Thanks,
Damien.
