I would say a cpu/cache issue. While it  complains about memory
Fault_PC 0x1035ec4 Esynd 0x0152 Slot A: J7900 J7901 J8001 J8000
it's unlikely that so many parts would actually fail.
If you want to test it without opening a ticket with sun, pull the board with cpu0 on it and see if the problem returns. If so, then it could be something deeper, if not then it's safe to say it's cpu0 and/or cpu0 components. 
I would just open up a case with sun, they can debug that error dump a lot more carefully than any of us can.

You have to open a case with SUN and give them the
core dump file or the log you included in this email.
I looked at your log and it looks like SUN needs to
replace the DIMMs J7900 J7901 J8001 J8000 as they had
multiple bits error. They may need to replace the
system board too.

You have faulty memory  on the primary system board in locations
J7900 J7901 J8001 J8000

It seems that you have a bad memory at J7900 J7901 J8001 J8000  J8100 J8101 J8201 J8200
at the CPU0 borad (the first one starting from down).
    To be sure of that, you can check it by removing this board and replacing it with the third board and starting the system with just 4 proc's, 8 GB and observe the behavior and if it did not crash
during two day's then the diagnostic above is right.

Don't know what the dump means but we have 2 v880's that have crashed 
due to dodgey memory (Samsung) if I remember correctly. Call them out 
and get it checked..

looks like there is are memory errors.... but they seem to come from 
different memory dimms.
i would start with most common one.  then move on to replace entire 
bank, if that does not work
replace system board.
try running vts for memory/CPU and it will not fail right away.... days 
with out an issue,. but when
it crashes while vts is running you have your bad boy. since you have 
warrenty let sun do the analysis
for you.

since the v880 is still under warranty support, cal sun support for
help.
at first glance, you have cpu0 reporting memory errors in a specific
bank of memory slots.

From: Tim Chipman <chipman at ecopiabio.com>
If the machine is still under sun warranty/support, get them involved 
ASAP.  The type of failure you describe is consistent with "fairly 
serious hardware failure" although it isn't inconcievable it is a 
software issue.  Usually a trivial way to distinguish the two would be, 
boot from an installer CDRom and leave the machine thrashing (copying 
junk data back and forth between 2 slices in an infinite loop or 
something) for a few hours.  If it crashes thus, booted from a clean OS 
of the installer CD, it would support the "hardware failure" 
hypothesis.  However, I expect you already have enough hints in the logs 
below for sun support to have a strong candidate "smoking gun".

This is a hardware problem.  Contact Sun immediately for service.

Install most recent recommended patch cluster from SunSolve,
in particular latest kernel updates. Install latest PROM patch
112186-15 (OBP 4.13.2)
(or later)
Download SUN VTS, install it and run it to check for hardware
errors. Look at /var/adm/messages* files and check for error
messages. If you have support download and install Sun Explorer
program and run it, then open hardware case with Sun tech support
and email them the output (a .tar.gz file)...they can check it
for config and hardware problems.

You probably just need to upgrade your Openboot version...
prtdiag -v | grep OBP
