Do you have AI aircraft enabled? I've been plagued with CTD's which had similar in the Log files, but have now found stability by removing AI Aircraft, specifically World Traffic AI from the Xplane AI Airplane menu.
Even with all plug-ins removed including World Traffic, I had the maximum number of World Traffic AI still defined within the AI menu (out of sight, out of mind).
With the AI removed I have improved stability significantly. The World Traffic plugin otherwise works fine, but I no longer get the World Traffic AI drawn on the G1000.
I'm doing more testing now with default AI and again with World Traffic AI but in fewer aircraft defined within the menu.
May not be relevant in your case but thought I'd share my experience.
