I have tracked my application using UMDH both in non-leaky case and leaky case and obtained the logs in both the cases. And compared the logs with UMDH.

When the problem reoccurred, resource manager reported multiple GB under Working set and Private bytes, but the UMDH snapshots account only for a few MB allocations in the process' heaps. At the top of UMDH snapshot files, it mentions "Only allocations for which the heap manager
