com.apple.mediaanalysisd files filling drive in macOS 15.1

Since updating my mac Mini M1 to macOS 15.1 on 28th October, my computer has been creating a 67.9 MB file roughly every hour when the computer is not in use in the following location: ~/Library/Containers/com.apple.mediaanalysisd/Data/Library/Caches/com.apple.mediaanalysisd/com.apple.e5rt.e5bundlecache/24B83/9CBD0F43A800584A3C4CABAFAE15CF754A6CC75117BE0645B8F09A3EF4974D11.

The files are in the following format, e.g. the latest one is BF43FD565F5326E554005345F8EE2E2C0271B9C0A9695FACB868D079B6B64D88.tmp.1443.bundle. As these are cache files, I deleted the Caches folder on 5th. November, when it had grown to 17.1 GB: since then, the newly-created Caches folder has grown to 3.16 GB. I have rebuilt the Photos library, also run Disk Utility over the drive. Note that this issue did not occur in macOS 15.0.1. Has anyone else experienced a similar issue, and possibly found a resolution? I have submitted a bug report to Apple.

Mac mini, macOS 15.1

I too have been having a similar problem. However, I am using M1 2020 Air.

Since I updated my software to Sequoia 15.2, the system data on my drive suddenly bloated to 110GB (previously, it did not exceed 25GB).

I tried cleaning my device using CleanMyMac, however, it temporarily reduced the space (to ~60GB). I hadn't used my laptop in more than 24 hours and when I picked it up - it was warm. As soon I logged in, it told me it was running out of space again. I checked CleanMyMac and could see that com.apple.mediaanalysisd is eating up 22.2GB and increasing.

What is this process? Is it a temporary indexing of my images? If so, does deleting it keep resetting the indexing and it would keep trying to run? My photos aren't even on my laptop so what on earth is it doing?
