Simplistically, a memory leak is where a program obtains memory to run, and at some stage should either stop requesting memory space, or at least free up some that it already obtained, but does neither. Instead, it tends to keep on requesting more memory, thus reducing available memory for other processes.
The GLANCE product helps here, as you can see per process what the RSS (Resident Stack Size ) is, and which process is using memory, and the one way to tell is where the memory useage of a process just keeps on growing!

Memory Leak occurs when your programs are running very slow and do a memory core dump.
You can find out by using sar, vmstat, top and the glance software.
sar, top and vmstat can be read up through the online manuals.
