Realm Swift abort() called - Encrypted db getting corrupted and can't recover

[palaniraja]

How frequently does the bug occur?

Sometimes

Description

We use realm encrypted db.

As our app works in background (read/write to db) and after a day or two it stops (crashed in background), and when we try to launch manually app crash due to db is corrupted. It is not always after a day, happens very random, still figuring out to get more information and reproducible steps.

Also reported to realm core - realm/realm-core#5190

### Can you reproduce the bug?

Yes, sometimes

### Reproduction Steps

Leave the app running, (updating db ~ once a min, (business logic) - and it db getting corrupted after a while

Frequency like 7 to 8 times a week. since db is encrypted we loose data

### Version

10.21.1 (via SPM) (most of our crashes) but also reported once with 10.1.4

### What SDK flavour are you using?

Local Database only

### Are you using encryption?

Yes, using encryption

### Platform OS and version(s)

iOS 15.x and 14.5.1

### Build environment

Swift package manager
xcode 13.2.1
