Hello Avery,

The largest object is 120M. I didn't describe the problem very accurately. The memory consumed is the *sum* of the objects downloaded.

For example, a repository of 4G consumes 4G of memory at the end of the receiving objects phase. What is very interesting is the total of objects downloaded is the same as the memory consumed. That makes me think there is a link somewhere. Surely it shouldn't consume that much memory.

I am ready to do whatever to diagnose the problem. I know C pretty well and am ready to look into it but I am not sure where to start.

Take care,
