Yes, it is on an UPS. But on this UPS there are 3 DS20E, 7 Compaq Proliant
server, 2 disk cabinets, .... all with no problems. So I think spikes aren't
the problem ... however I'll ask netwerk services about monitoring the UPS.
Just asked about the UPS ... it converts AC to DC and DC to AC (permanent)
so spikes are impossible.
The floor is concrete! The last few times the problem occured was during the
middle of the night or in the weekend ... no one around jumping on the floor
,-).
Murphy ?? We think he is living here, but we are lucky, sometimes he is on
hollyday ;o)
All CPU's are going the be replaced and the batteries of the MA8000.
The machine doesn't crash, doesn't reboot it just freezes
Thanks
