I confirm the bug conceptually (did not reproduce).
Call it memory leak...
Did you realize that incidentaly or have you seen an anomalous growth of interaction number in a simulation?

I wonder how it can be solved without hacks. The notion of multiple
physical interactions between two bodies does not fit very well in
Yade's picture at the moment.

Title:
  Sphere - nonSphere interactions never deleted by
  Law2_ScGeom_CapillaryPhys_Capillarity

Status in Yade:
  New

Bug description:
  Hi,

  Let say one performs simulation with
  Law2_ScGeom_CapillaryPhys_Capillarity and
  Law2_ScGeom_FrictPhys_CundallStrack.neverErase = 1 (in order to keep
  menisci between separated particles)

  In such case, interactions between sphere and non spherical particles
  (e.g. boundaries) are not deleted by
  Law2_ScGeom_FrictPhys_CundallStrack when geometrical contact is lost,
  and are neither handled (deleted because of no meniscus, in
  particular) by Law2_ScGeom_CapillaryPhys_Capillarity because
  Law2_ScGeom_CapillaryPhys_Capillarity simply disregards such
  interaction [*].

  And the user ends up with much more interactions than necessary..

  I'm filling a Bug report for the record and possible discussion about
  desired behaviour (sorry I could not provide a MWE !)

  Jerome
