I think, it is "connected" with python-variables.
Removing the python variable should destroy an object (need to try):

b = utils.facet()
id = O.bodies.append(b)
O.bodies.erase(id)
b=0

You can try such approach. Maybe it will help.

Title:
  memory leak while erasing facets

Status in Yet Another Dynamic Engine:
  New

Bug description:
  I detected a memory leak in O.bodies.erase, when facets were erased (spheres are erased without memory leak!).
  In the attachment you will find two files, where you can reproduce the bug.

  1. Open a terminal with three tabs.
  2. Run top or htop in the first terminal tab
  3. In the second terminal tab run yade input file "memoryleak-erase-facets.py"
  4. Get the pid from first terminal tab (example 31667) and edit "get-memory-info.py"
  5. Run "python get-memory-info.py" in the third terminal tab and wait (ca. 5 min) to the end of the calculation.

  You will get an output file called "fig-memoryleak-erase-facets.png",
  where you can see the effect of the memoryleak.
