I'm running NetBSD/sparc 1.5.2 on a SS10 and recently messages like 
this have been appearing intermittently on its console:

Async registers (mid 0): afsr=0<AFA=0>; afva=0x00
NMI: system interrupts: 10090000<VME=0,SBUS=0,E,T,M>
memory error:
         EFSR: 9e11<CE,DW=1,SYNDROME=9e>
         MBus transaction: 8ff0cd30<VAH=0,TYPE=3,SIZE=5,C,VA=c3,S,MID=8>
         address: 0x0ad6e7c0

         address: 0x0ac067c4

Presumably this means one (or more) of its SIMMs is about to fail? 
Is it possible to tell which one(s)?
