Summary0005764: Random crashes when a lot of lights are present in complex scenes
DescriptionTDM will randomly freeze or crash in some complex scenes. Particularly ones with a lot of lights, given I'm noticing this while testing my irradiance lighting mod which adds a bunch of ambiental lights. The crashes appear random and not consistent with any certain trigger (eg: looking at one thing from one angle would always produce it), will occur in roughly 1 to 5 minutes of playing. When running TDM from a console this is the relevant output it exits with... I also attached Darkmod.log albeit it doesn't seem as relevant:

signal caught: Segmentation fault
si_code 1
Trying to exit gracefully..
double fault Segmentation fault, bailing out
shutdown terminal support
About to exit with code 11
Steps To ReproduceI'm currently only able to reproduce this on a larger and yet unreleased FM I'm working on. I advice bringing up a complex FM with enough polygons, placing a lot of long-radius lights all across it including ambient cubes, then noclipping throughout the map for several minutes: The lower your FPS due to strain the likelier this crash should be. If you can't make a test case, let me know what extra info you need from me producing it.

Not sure if in any way related, but a while before the crash I also saw the following message printed:

Resizing dynamic VertexCache: index 65536 kb -> 131072 kb, vertex 65536 kb -> 32768 kb

Does this also happen without your custom lighting patch? Multiple ambient lights are not the norm in TDM.

Try increasing:

r_frameVertexMemory
and
r_frameIndexMemory

to 16384

so that the resize will not be so dramatic

Darkmod.log is useless.
Better attach condump obtained using logFile 2.

If you cannot provide your map, then you can at least record a crash dump and given it for inspection.

Sorry for being slow to get back to this. Just checked and noticed both r_frameIndexMemory and r_frameIndexMemory are already set to 16384 for me.

I should note I've seen similar crashes even without my irradiance mode installed, albeit far more rarely so they're even harder to reproduce then. This includes a smaller FM I'll hopefully be ready to publish this month.
