--- Comment #57 from Sigmund Hansen <apple at sigmund-hansen.com> ---
On one particular phone running iOS 16.4.1, we were seeing the "UnknownError: Connection to Indexed Database server lost. Refresh the page to try again." error. After getting access to the phone, I found there were JetsamEvent logs on it, and could see Low Memory warnings in Instruments' Activity Monitor. I'm guessing the SQLite/IndexedDB Process was chosen for eviction in this case. It was easy to reproduce, after performing about 20-50 transactions this would consistently occur.

After I deleted all locally stored data from Safari. The issue disappeared. There was only about 30 MB of locally stored data.

This particular phone was a tester's phone, which is only used for testing, so it doesn't have a lot of apps installed either.

We are going to try and reproduce it. And I'll upload some JetsamEvent logs for you to analyze as well.
