Memory Leak when animating with SI 2015

[Andres Stephens]

I don't have many details on it, but I found SI hogging nearly 80% to 90% of my ram after animating an hour or two. I use GEAR rigs, yet I have no other idea what would cause this memory leak.

Any pointers as to how I would troubleshoot that in SI 2015?

Thanks in advance

Here is an example of the memory leak.

I found out that this happens when I play animations on loop over an over again, eventually eating up all the ram and nearly forcing my OS to freeze.

Fixes? How can one dump the memory cash for animation playback?

Out of curiosity, are you using "Fast Playback 2D|3D Wireframe" ?

I was not at the time. Should I have it activated at the time of loop playback to see if that doesn’t give me the memory leak? I’ll.. give it a try. I feel I’m shooting in the dark here.

This is all with one character, I’d hate to have this happen during crunch time.

I was just wondering if it was on and causing it, I'm shooting in the dark here too. 

How fast is it leaking...how many frames does it take to be noticeable?

Good “shot” I suppose.

I animate between 40 to 120 frames, and it will start to eat up the ram after about 5-7 consecutive loops.

Normal playback from beginning to end does not do this. I have avoided the looping over and over again and apparently I have no more leaks, back to my normal 1-2 gigs of ram usage.

I wonder if it’s the rig - or SI? Do you want to take a look at one of my scenes that eats up the ram?

[Rob Chapman]

Without any reproducible examples it is going to be hard to nail this one down.  Is there a memory increase if scene is playing back on loop?

[Andres Stephens]

Here is the scene file.

It has an animated frog in it - not the best I must say, but something!

**I would appreciate if you guys don't really use it for anything, as it's not really my design or property to share, but just for troubleshooting cases.

So, now that is cleared, memory leak happens with extensive animation playback repeats or loops - shift in view during playback, etc.

Eventually all my ram is chewed up after prolonged animation playback. I do notice that my ram quickly clocks up during playback, not dropping down upon pause/stop.

Thanks for taking a look at it.

tested and i can confirm, just open scene put play and loop and ram goes up and up and up....

Thanks Jill, for taking a look at it.

Can you please remind me how to submit a log? Is there a website where I can fill in details to submit?

I think there is, I just.. didn't save the link and can't google it.

SI does not crash and do it's automatic "submit report" dialogue - so I haven't submitted anything, thus being here.



Thanks in advance.

I have been doing more tests, and it seems it may have something to do with the rig.

Upon making keysets, and modifying some contraints it seems I created a leak. My other rigs do not have this problem. I am trying to start again and find out what went wrong.

Hi Andres,
You can report the bug here: http://download.autodesk.com/us/support/report_a_bug.html?SelProduct=Softimage

Thanks,

[Hsiao Ming Chia]

I can definitely see a jump in memory usage during playback, and it does not go away on a new scene.
Thanks for reporting.
We will be investigating this.

Thanks,
Hsiao Ming

We have not found the cause yet though freezing the ICETree op (Rana_01_-_ver-05.mouth_C0_jaw_ctl1.crvlist.ICETree) seems to stop the memory bloat.

Ah yes, you beat me to sharing the solution. I figured it had to do with that tree.. I was using the icetree to drive a few parameters, like as if in expressions. There must have been a circular reference..

I removed it entirely before you mentioned this and it fixed the issue..

Thanks for the help.
