    I'm trying to track down why certain objects are lingering in memory. As I walk up the references, I eventually land at this:

    What does this 'unknown' object indicate?

    While I can't say for sure in your case, I have seen this for references from static fields. The profiler logs the connection between the object and the class (which has a ref to the object) but there is no view that displays the class with static fields currently. There is only all objects, and all managed types (Table > Raw Data > Managed Types), but the managed types table is not expandable per class.

    @MartinTilo , I still see this with IL2CPP actually. I'm not sure if these are static fields; it's possible, but I haven't tracked it down yet.

    @briank Thank you for pointing this out, we are planning to do a sweep over this behavior and unify. Unknown could also mean a datatype that is not accounted for in the package logic.
