Large Database.db Size

Just wondering if I’m the only one that’s ever observed something like this:
Our Database.db (LiteDB5) size has somehow managed to grow to over 5GB. I had suspected it was growing due to a lot of retained jobs and logging targets set to retain 365 days, but both of those have been corrected. File size has been static at around 5.77 GB (6,196,813,824 bytes) for a couple days now. Anything obvious I should be looking for?
