Maybe try taking out one of the sticks of RAM and see if it installs and then once it's installed, put the RAM back in and see if it's stable. If it's starting spewing garbage all over the screen every time you do a ZFS zpool scrub after putting the stick of RAM back in then the stick of RAM is definitely part of what's causing the problem.
Sometimes even my Ubuntu RAM tester wouldn't "see" which stick of RAM was giving me problems and I would have to resort to pulling out random sticks of RAM and seeing if the system became more stable or not after the RAM was removed (I've had to do this before with both OpenSolaris and with servers taking heavy loads that were based on Linux distros like Red Hat and Ubuntu). FYI: OpenSolaris 2008.05 runs fine on 2 gigs of RAM, it's only when you have less than 1 gig of RAM that it starts swapping like crazy and you run in to serious speed problems. If still none of this helps, try out a different OpenSolaris based distro like Milax or Belenix or Nexenta (I hear lots of good things about Milax all the time) and tell me how it goes. -- This message posted from opensolaris.org
