Solaris will use all available memory for buffers and caching, thus
monitoring free memory is quite pointless. What you do want to keep
an eye on is your paging activity. For more information I'd recommend
Adrian Cockrofts excellent "Solaris performance and tuning" (I think
it is called) book.

Also, note that the total internal memory used by processes may exceed
your RAM size due to memory being shared between several instances of the
same process.
