hello managers,
this was a memory error in some cache, which was corrected by the
ECC hardware on the board. there seems to be no problem, as long
such messages do not occure often, which they currently don't.
in case i see this more often, i could try to:
* reboot. maybe the problem simply goes away.
* reseat the simms.
* call deq for service. they will probably replace simms.
many thanks to:
