@iangilman it definitely happens when the image goes partially offline.
using the debugMode flag makes it clear

@iangilman opened the issue (openseadragon/openseadragon#1211). I'm going to update it if further informations come up in debugging.

Is anyone able to explain why the tile cache release cutoff is set this way in TiledImage? https://github.com/openseadragon/openseadragon/blob/master/src/tiledimage.js#L1470-L1474
If, for example, I have a tile size of 256 in my image any tiles in level 8 or below of the tile source will never be released from the tile cache. That seems incorrect to me and it's causing some memory issues after navigating around an image for a while. Maybe I'm missing something?

@sickrandir Great, thank you :)
@seanich I guess that's meant to make sure we never lose the "master" (a tile that includes the entire image). Seems like maybe it should be updated to be more explicit about selecting the largest level where the entire image is a single tile, like my recent change here: openseadragon/openseadragon#1198
