Just to perform a test, you could try loading up the pool with as much test data as you can (some repetitive incompressible test pattern would be best, e.g. a movie file) and then run "zpool scrub" to verify all the checksums. > 4.

This could indicate degrading or failing ECC memory. Try running memtest86+ on the machine for a while to see if it reports anything useful. You can grab a pre-built ISO at http://www.memtest.org/#downiso Alternatively, grab a bootable file from that site. Then, just put it somewhere on your root filesystem, e.g. /platform/i86pc/memtest86+-4.20.bin, gunzip and boot to it from GRUB by entering the following GRUB commands: findroot (pool_rpool,0,a) <- partition number + slice bootfs rpool/ROOT/omnios <- see "beadm list" for the exact name kernel /platform/i86pc/memtest86+-4.20.bin boot > 5.

System crash dumps are usually saved on the dump device (rpool/dump) until you manually retrieve them. If you run "savecore" without any arguments it will try to extract the crash dump from the dump device and save it to /var/crash/<hostname>.
