memory leak is a progam that consists of repeatedly allocating memory, using it, and then neglecting to free it.
one way of identifying memory leaks is to first locate the process that you expect causing the problem! (you might look into the highest RAM-utilization svmon -P -n -w -v) man svmon for more info.
Then using the PID of that process do this:
svmon -P PID#
and watch the inuse column for any segment that continues to grow! (watch for the segment 0 (kernal) & segment 2 (user stack & data).
