I added a debug message to

But it looks like you didn't add a message to end_free_itds(), so we
don't know when the memory gets deallocated. And you didn't print out
the values of urb, num_itds, and i, or the value of itd (so we can
match up allocations against deallocations).
OK, I will implement this more detailed logging. But with several
allocations per second and runtime of several hours this will result in
a very long logfile.
If the memory really is being leaked here in some sort of systematic
way, we may be able to see it in your debugging output after a few
seconds.
