Brief summary:
Internal sun tool called RMCBunyip, which has usefull stuff.
/usr/dt/bin/sdtprocess (which I don't seem to have)
/usr/proc/bin/pmap [-r] [-x] <PID>
Try proctool which is freely available at
ipcs -a
sar -g 2 100
/usr/ucb/ps -aguxw
ps -eal | cut -c43- | sort | tail

proctool and memtool are very cool, and pretty close to what I was looking
for. RMCBunyip appears to be the same as memtool.

Based on sar and SE toolkit output, yes, it really is paging. We're still
trying to figure out why, but with these URLs and tools, it should be
easier to solve.
