ObjectAlloc can tell you that.
Or I think Instruments can too, if you're in Leopard.

How do I figure out what the objects are that were allocated? It's
hard to debug when all I know is which method was called...

You could use MallocDebug to show you where all the allocations are
coming from, if the problem really is allocations.
Allocations aren't considered leaks if you are holding on to a
pointer to them, so "leaks" won't find a lot of simple problems (like
if your code is accidentally growing an array or dictionary larger
and larger and larger without ever shrinking it back down).

When my application has been running for a few minutes, Expose
starts being jerky. My app takes almost 0 CPU. However, its real and
virtual memory usage keeps increasing. I used Instruments to check
for leaks and eliminated all of them. When I run leaks, the output
is something like this:
Process 327: 16547 nodes malloced for 2067 KB
Process 327: 0 leaks for 0 total leaked bytes.
When I quit my app, Expose starts working normally again. Yesterday
I left the program running all day, and came back to my computer
being at the login screen; I tried to log in again and it froze.
After restarting, the console was full of these messages:
kernel proc: table is full
Is this a memory issue or something else? How can I accurately debug
this?
