From a reply when it happened to me on a particular machine (now decomissioned): ---- 99.99% of the time when you see a RED State exception it is either the CPU itself or its ECache. Since, if I've read the rest of the thread correctly, you're only seeing it under load it sounds like it's likely the ECache, not the processor itself. ---- kris --1yeeQ81UyVL57Vl7 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQFBgp8BWry0BWjoQKURAhdpAJ47HQ14I/vM3PWWMG92Ubej29qzgwCdFT0n 4iQxFirALl9JtyLJwnYhHH0= =tVBf -----END PGP SIGNATURE----- --1yeeQ81UyVL57Vl7--
