If you have ``logic parity'' instead of true parity you have defeated 75 % of the purpose of even having parity on memory. I would highly encorage you to try a swapout with some ``real parity'' memory and more than likely watch your problem go away... -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
