Yesterday a PWS600au I manage paniced and went to the SRM prompt.
I had gotten what I thought to be memory errors from that machine
for a while now and was in the process of figuring out what
memory modules to replace. But it never paniced before and now
I am not sure anymore if these really are memory errors or
something worse. I attach the corresponding output from the
binary errorlog and /var/adm/messages. I would appreciate
any help deciphering them.
BTW, I got a few hundred binary errorlog entries like 1387
within the last few weeks but the machine never paniced.
They usually happened under high load which made me suspect
the memory.
Thanks
