FastMM : Tracking a running memory leak

Hi all,

With the help of FastMM, I can get detailed information about memory
chunks that have been allocated and never freed. This way I managed to
get zero leaks at the end of my program.
However, if kept running, its reported memory usage is increasing
steadily so I suspect there is somewhere a chunk of memory that is freed
too late.
Are there some options in FastMM to report the memory usage during the
time life of the application?
Or is there another tool to do that?

Thanks in advance.
