Annoying little error message you may find lurking in the vmcore file following a mysterious crash of your Sun Microsystems Enterprise server. This may or may not indicate an ecache problem on one of your cpus. It may indicate the presence of evil gerbils tapdancing across your system board - who knows? The good folks at Sun will advise you to wait around for the system to crash again on the same cpu. And then they'll replace it. At my place of employ this is cause for big laughs among the Windows NT Administrators, who are used to their crappy operating system blowing up on a daily basis.
