The two immediate possibilities that come to mind:

  1. Your object graph is massive, and serializing it literally does cause the DataContractSerializer to hit some memory limit
  2. Your object graph has a circular reference, and serializing it causes an infinite loop of serialization that results in consumption of all memory

I'm not entirely sure the second item is actually possible, because the MobileFormatter should be flattening the object graph into a list, and converting all object references into numeric position values before serialization begins.

So you might want to upgrade to version 4.3 and see if the new binary reader/writer solves the problem. They result in much smaller serialization results, and therefore might avoid the issue.
