Skyrim crashes (Windows hang, not CTD) after playing for a while

[dragongrunt]

I recenlty jumped into the SMP wagon, and while I really like how nice the clothes behave. Unfortunately I stumbled upon a new issue (new for me).

 

After wandering for a while and just while standing (playthrough with no fast travel)  or navigating through my hairstyles catalog (who doesn't have more than 1000 hairstyles), my game crashes with Windows prompting me to close the game and to report the problem. You know the old Windows app crash, not the kind of CTD Skyrim usually performs. When I read the crash report, it says the hdtSkyrimMemPatch.dll is the module at fault. The hdtSkyrimMemPatch log does not have any indication of error.

 

Windows event viewer shows this:

I've been playing my Skyrim for at least two years with almost no CTDs nor other issues ever crashing my game. Got a lot of mods, fine-tuned my enblocal and I'm using the SKSE mem patch. But using SMP triggered this kind of crash I haven't experienced before (besides the pure virtual function call crashes, which long ago were the most annoying). My guess is as the game allocates more memory, something brakes and crashes the whole application. Not even papyrus has a chance to save the log.

 

These are my SKSE.ini settings:

[General]
EnableDiagnostics=1
ClearInvalidRegistrations=1

[Display]
iTintTextureResolution=2048

[Memory]
DefaultHeapInitialAllocMB=768
ScrapHeapSizeMB=256

 

I have this setting in my enblocal:

ExpandSystemMemoryX64=true

I had to enable this setting because 4K textures would not load (black polygons) unless I approached the object/NPC. It was very immersion breaking.

 

I'm fairly sure I need to tune my hdtSkyrimMemPatch ini to get along with the other plugins. However I don't know exactly what every line in my hdtSkyrimMemPatch.ini does. I'm using the HDT-SMP along with HDT-PE. Both are working without issues. SMP clothes cause a very slight frame rate drop under very specific conditions, but I can live with that.

 

I hope someone can guide me to correct this issue. Or if you can point me to a hdtSkyrimMemPatch settings guide, that would also be helpful.

 

My current hdtSkyrimMemPatch settings (by default):

[Exception]
AutoSaveGame = true
MiniDumpWithFullMemory = false
ReportToWindows = false

[Memory]
RecordFormHeapAllocateFailed = true
FormHeapAllocateFromLargerSpace = true
FixInfiniteLoad = true
ReplaceDefaultHavokHeap = true
doNotReleaseHavokResource = true

[Optimize]
FasterLoading = true
UseShaderCache = false

[Camera]
fix3rdPersonCameraScale = true

If any log or file is required I can oblige.

 

Thanks in advance.
