Perhaps you haven't set any kernel tuning parameters. Per default MINPERM/MAXPERM is 20/80, try 10/40 and monitor the effect.
Also the MINFREE/MAXFREE parameters may have to be adjusted, but without more information i can't give you any detailed advice.
Use "/usr/samples/kernel/vmtune" (better consult the manpage before, this can send your machine to electronic nirwana) to set kernel tuning parameters.
You can use the vmtune utility to change parameters only until the next reboot. If you want your parameters to survive the reboot put them into an rc-file.
Btw. it is expected behavior that your machine doesn't have more meory free - AIX doesn't want memory to go wasted and will it assign to *any* task before leaving it unused.
