Thanks for the tip. Unfortunately it shows the same exact

I'll have a look at the SE toolkit - thanks.

vmstat shows me this:
# vmstat -s

I've not much experience with this, it looks like there are
considerably more page ins than outs as compared to our other
solaris boxen but otherwise pretty normal.
