Memory leak

Download link for output log, saved games and craft files.

Didn't experienced such heavy memory leak for a while. Playing with this mods for a month, usually game is stable enough for one hour or two, but this time crash in less than 2-3 minutes. As you can see on pictures(memory usage shown on left side), memory usage increase every few seconds until game crash. There is persistent save game and quicksave with plane in flight that need to land near contract spot.

 

Spoiler section contains list of installed mods. On top of that is also latest FAR development release from github. Output log file didn't gave me a clue for possible reasons behind CTD. Does someone have idea what can be reason behind this, so I can avoid it somehow ?

EDIT:

Nevermind. Figured out. It was terrain detail set to max. Too many trees comes to vison range. Each time some tree become visible it consume small chunk of memory. It would not be much of issue if trees that goes outside of vision range release used memory. That never happens and RAM is filled up too quick in some areas of planets.

I have set terrain detail to low and same save game is playable again without memory leak.

found reason for bug

Have you tried this stock to establish it is not a mod interaction?

Have you tried this on other planets to see if it is scatters in general that cause this or just the tree?

If so, you should report it on the bug tracker. The more memory leaks that can get plugged the better.

 

Well caught.

[kcs123]

No, I didn't tried with stock only game, I need at least MM and graphic memory monitor to be able to detect memory leak. I didn't tried on other planet, for that I should also need hyper edit or similar mod at least to get there, as my career game is still early.

However, I'm sure that is trees causing memory leak. I have landed that craft showed on galery trough repeated quicksaves in landing sequence, just before game CTD.

Once craft is landed, there is no memory increasing. But when I rotate view around craft and trees trough scene rotation comes in field of view, memory increases more and more until CTD. After that I have reduced terrain detail and tried the same thing on the same land spot.

With low terrain detail it is hard to notice increase in memory usage due to low density of trees, but memory is still increased over time, just with much smaller chunks.

Don't know if SQUAD have interest to investigate this, they have switched to Unity 5 game engine, so same issue might be already solved.
But it is something worth to test prior 1.1. release, to be sure that old bug is not sliped in somehow.

I'd like to know if this is fixed in KSP1.1/Unity5 as well.

I'll try to reduce the terrain scatter, thanks for the tip.
