On one of our production servers, w3wp.exe uses >600 MB private memory for an ASP.NET Core app.
I did a managed memory dump with dotnet-gcdump yet that one one shows about ~23 MB memory usage from managed objects. I also took a full memory dump but didn't see high memory usage by anything I could access.
Doing the gcdump should have cleaned up any unused memory, right? So something is still actively using all these MBs?
What could be going on here?
