<div dir="ltr">Josh,<div><br></div><div style>VTK/ParaView uses reference counting. So as long as a there's a reference held to any dataobject, Delete() is not going to release it. Barring cycles, a quick way to see if Delete() will result in clearing the object, is to look it it's ReferenceCount member variable before calling Delete(). However if you're passing the data allocated as output from your filters then the reference maybe getting held by the pipeline beyond your control. If you can share the code, I can see if I can explain why the memory may not be getting released.</div>

Currently after I purge my cache (I am calling Delete() on all of the objects and destroying the remainder of the cache map) the system memory does not free up… ParaView remains in control of all of the memory for the dumped cache items, and when the new cache is introduced, the memory usage just keeps going up.</div>
