I'm also experiencing CTD issues in flights from KSAN to KLAX with FF767-300ER. No information in the log, it's not flushed and probably misses the latest entries. No file in Output/crash_reports either.
Using X-Plane 10.45r2 on Win7 x64. The only add-ons is X-Camera, I'm not using SMP. With 16 GB of memory, I seriously doubt it's a memory issue, but to be honest I haven't monitored X-Plane's memory usage. The virtual memory could go up to 32 GB with my current settings, if it were a memory issue I would have noticed the disk starting to go mad.
I proceeded to a few tests, always with the same flight plan:
- same flight with a default aircraft ("P180 Avanti Ferrari Team" "Cirrus TheJet"), no weather, but keeping sceneries => CTD
- same flight without any scenery, FF767 => no CTD
- re-introduced "KSAN - San Diego International 1.01" by MisterX6 alone + dependencies => CTD (with FF767 and default aircraft)
- used another KSAN (by jkotva22) => no CTD with FF767
- used "KSAN San Diego International Airport 1.02" by ThePrivateer => CTD
Depending on the scenery, the crash always occur in the same area, for example with MisterX6's, and KSAN-LNSAY.SLI-KLAX, it's around the Bayer waypoint.
So I don't know whether it's the complexity of the origin airport + destination area (Los Angeles causes frequent stuttering and freezes becausee either X-Plane is unable to manage a smooth loading of the scenery items, or the autogen, or yet another issue, I have no idea), or a dependency like OpenSceneryX, or another bug in X-Plane triggered by something common in both airports.
This should really be done in a debugger environment as I believe we don't have the tools to get further information on those crashes.
