I appreciate the link, but I actually had read it; the problem is that I don't understand what the timeline view is showing me. As time goes on, the object allocations increase monotonically, which means I'm leaking like a sieve somewhere. Leaks' timeline is flat, except for periodic triangular spikes that rise up high, and then fall back to 0. I'm trying to figure out what that information is supposed to mean; does it mean that I'm only leaking during that time period, or does it have some other information? I guess what I'm expecting to see is a graph of the total number of objects leaked so far, not a 'velocity' of leakage.
Thanks,
Cem Karan
