I have a hybrid iOS app that continually is crashing, I have posted a crash report for this issue before. It appears to be happening when it is trying to save data to storage, it is taking all the data and attempting to convert a large object to a JSON string with the built in javascript Stringify method. Is there anything that sticks out to anyone? Original app name is redacted.
Yes, the app is running out of memory:

Also, you should switch from using UIWebView to WKWebView. Aside from stability and security improvements in WKWebView, the com.apple.WebKit.WebContent process may have more memory available for this operation than your app process.
