Hi, I noticed this logged in /var/adm/messages on Ultra 10 (dual boot
Solaris/NetBSD) while running Solaris:

SUNW,UltraSPARC-IIi: [ID 657638 kern.info] [AFT0] Corrected Memory Error

SUNW,UltraSPARC-IIi: [ID 705825 kern.info] [AFT0] errID 0x000058ad.4cfd3df5 ECC
Check Bit  0 was in error and corrected

I am a bit confused, is this message related to ECC error correction or does
this indicate faulty memory?

Which brings me to another question: how would this affect NetBSD? What I mean
could this result in system crashes/freezes that I've been seeing with threaded
applications?
