FileSystemException: Cannot open file OS Error: Too many open files, errno = 24)

## 🐛 Bug Report

### Expected behavior
Load image list

### Reproduction steps
More image cache lists are loaded at the same time

### Configuration

**Version:** "3.4.1"

**Platform:**
- [x] :iphone: iOS✅
- [ ] :robot: Android
error
```
FileSystemException: Cannot open file, path = '/var/mobile/Containers/Data/Application/OI897JGR-7196-OI897-B008-OI897JGR/Library/Caches/libCachedImageData/9d864c1c4ef0.jpg' (OS Error: Too many open files, errno = 24)
```

Start by reproducing the iOS failure described for version 3.4.1 while loading multiple image cache lists at once. Trace the cache-manager path associated with the reported libCachedImageData file and determine where the open-file limit is exceeded. Done means the image list loads without the errno 24 exception under concurrent cache loading.
