If you are leaking in the C program (I am assuming it is LE) then you might see just some large chunks allocated to the heap (subpool 2 maybe....not sure). If that is the case then maybe the VERBX LEDATA IPCS command will help (IIRC you will have to provide the TCB address). Disclaimer : I am a complete noob as far as C is concerned.
If you have a more "traditonal sytle" leak - then this might be evident in the other (non-heap) subpools and VSMLIST will show you some clues.

I've never used IPCS :-( But I'm afraid in this case I have to use it.....
