freebsd-sparc64 Digest, Vol 63, Issue 4

[Mark Cartwright]

Heya.  I'm not a developer, so can't speak to all
possible causes of this (such as actual kernel code,
etc), but I am a pretty proficient Sun guy so can
speak on at leas thte first part.

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.

Hope this helps.
