Hi, still having this problem, even with default sysctl values. Just not as often and not as fast (after a reboot).
According to (hope thats the right doc) http://www.sun.com/processors/manuals/cs_plus.pdf it sounds like this should not happen at all. At least to me it sounds like a bug. Would be nice if someone could look into that.
