In the Solaris 9 9/02 operating environment, on UltraSPARC II-based systems, the CP Event message that accompanies some Uncorrectable Memory Error messages is not always produced. These systems include the Sun EnterpriseTM 10000 and Sun EnterpriseTM 6500/6000/5500/5000/ 4500/4000/3500/3000 systems. The result is that some information needed to identify a failing CPU might not always be present.
