Memory usage under Linux is a tricky thing.
It depends if you're looking at RSS (RES in top), which is the actual
RAM used by the process, or virtual memory (VIRT in top) which actually
may map directly to disk and/or to RAM, and/or be shared with another
process!

A typical usage of a process the RES will rise, and then hit a plateau.
Check the memory usage after a day, it should be the same the following
week.

If the RES raise linearly for days until the system trashes, you may
have detected a memory leak.

But to make sure a leak happens, usually tools like Valgrind helps
better than looking at what the kernel reports, as there is a lot more
hidden than what shows.
