full jetsam event from device

On low-end devices such as iPhone 5c and iPad 4th generation the web content process crashes when a WKWebView loads complex SVG content.
This sometimes also causes a crash of the UI thread as seen in - https://bugs.webkit.org/show_bug.cgi?id=162265

Attached is one of the jetsam events that was added to the diagnostics following the crash.
No crash dump of the WebContent process itself, but the jetsam event says it's related to vm page shortage.

Thank you for the report!

Is there any way for us to reproduce (e.g., is this reproducible in Safari)? Have you tried with iOS 10.1 beta?
