[MonoTouch] App is crashing at random - the app completely freezes indefinitely

[MilkyJoe]

frozen for a few days, but it just did with:

I log the View events, so that I can determine at which point the app locks
up. It looks to be triggered by low memory, but I can't figure out what if
causing the problem.

>Also, if you google for the warning you'll see that it looks related to
UIWebView.

Which phrase did you google on Rolf?

I didn't seem to be able to get the symbolicated version of the log. The
previous extract is how it looked it XCode.
