Hm.  We have a sun4 here with similar questions.  It has 128meg of memory
(yes, really, it's 128meg ram and 3.2gbyte of disk).

Many of the programs we run are upwards of 12 meg.  Unix will only let
them have 8 meg at a time though.  Is there a reason for this or can we
fix it by reconfiguring the kernel?
