Cached Media gallery disappeared.

[ara4n]

Steps to reproduce

1. I opened the media gallery in Element X Internal
2. I waited the ~30s needed to backpaginate and load a full screen of thumbnails on my Max size screen
3. I admired the gallery
4. Use the app a bit. I didn't open any other galleries or increase my caching particularly though.
5. A few hours later, i reopened it, to demo how fast it now is!
6. ...except it had forgotten everything and started over :(

Outcome

What did you expect?

Gallery to be backed by a persistent event cache, which should hang around for quite a while.

What happened instead?

Cache went boom for reasons unknown. (I'm a bit low on disk space, so might be that?)

Application version

847

Will you send logs?

Yes

Nothing looks particularly wrong or bizarre in the rageshake, on the SDK side. We have builtin resiliency, when reloading an event fails we'll clear the storage for the room it comes from; but that doesn't happen here in the attached rageshake, since we'd log an ERROR statement in this case, and I couldn't spot any related to the SDK being unable to load from storage.

For a media to disappear, we'd need the media events to disappear. So I wonder if the OS/app decided to get rid of the event cache DB in the background because storage was low; or if the persisted storage has been disabled and reenabled (doing so would clear it as well).
