I don't believe the three swap areas should have any affect on the overall
swapping or should bother the system. Although I would remove the "swapon -a"
from the rc.local, you don't really need it. And for simplicity sake your
entries in /etc/fstab only need look like the following:
/dev/ra1b::sw:::::
/dev/ra2b::sw:::::
The system only cares what partition when it sees the "sw" in the type field.
The way to find out if your "configured" swap areas are seen by the system is
to check two lines when you do a pstat -s:
131072k swap configured
57162k used (12668k text, 1312k smem)
75408k free, 12060k wasted, -1498k missing
avail: 36*2048k 1*1024k 2*128k 1*64k 3*32k 7*16k 128*1k
131072k swap configured
^^^^^^^^^^^^^^^ shows how much swap you should have, in this case
/dev/rz0b and /dev/rz1b (rz55's)
57162k used (12668k text, 1312k smem)
75408k free, 12060k wasted, -1498k missing
^^^^^^^ shows how much is not
recognized by the system, this means it's configured but not in use.
avail: 36*2048k 1*1024k 2*128k 1*64k 3*32k 7*16k 128*1k
