LTX-2 crashing at VAE decode since dynamicvram mode

[lebakerino]

Hi, I'm using Comfyui via Stability Matrix and have been using it with LTX-2 since release with no major issues like this but since the dynamic vram upgrade which has been very handy, there has been this issue of right at the end typically I think when saving video as I see the file be created in my folder but it is a dead file, ComfyUI basically crashing and it's happened maybe 40% of the seperate occassions I've generated videos since this issue began, earlier on I had 2 BSOD's but that might have been because at least on one I opened another application when it was saving (it noted the app that I loaded in the windows report.

I had thought maybe it's due to me 'using' the computer like switching a tab at the end (I usually minimize or switch tab from comfyui as having it open appears to use unnecessary GPU power, like just having the window open I've seen it use 40% of my gpu even with all workflows closed..) to check how close it is to finished was causing it but even when I am away and leave it entirely sometimes it happens and sometimes I can have a queue of videos and it does them all just fine

I've tried all of the tiled VAE's, I typically use the Beta node but it happens with both of the LTX nodes too so I'm not sure if thats the isuse.

(I'm on Windows 11, Stability Matrix, latest version, latest nodes, everything up to date. Also should note my paging file was automatic, though I've today reduced it to 50gb max to see if it makes things more efficient but it hasn't affected this issue)

After it happens, the log shows: a stream of this:

00000002B5B7E000

and the error popup reads:

[rgthree-comfy] Loaded 48 extraordinary nodes. 🎉

[rgthree-comfy] ComfyUI's new Node 2.0 rendering may be incompatible with some rgthree-comfy nodes and features, breaking some rendering as well as losing the ability to access a node's properties (a vital part of many nodes). It also appears to run MUCH more slowly spiking CPU usage and causing jankiness and unresponsiveness, especially with large workflows. Personally I am not planning to use the new Nodes 2.0 and, unfortunately, am not able to invest the time to investigate and overhaul rgthree-comfy where needed. If you have issues when Nodes 2.0 is enabled, I'd urge you to switch it off as well and join me in hoping ComfyUI is not planning to deprecate the existing, stable canvas rendering all together.

Which VAE Decoder node type are you using?

Ideally can you send me the full workflow or at least a screenshot of the node that is crashing.

[rattus128]

It sounds a bit like youve tried every VAE node you can find for the same result, but just confirm for me what your main goto VAE is so I can dig a bit harder on one.

[rattus128]

Could you try --disable-cuda-malloc startup argument and see if that helps? LMK the results, this isnt a long term solution but will help corner the bug if it helps you.

Yes as I mentioned, I have tried it with all tiled VAE decodes, the beta node and both LTX nodes.

There is also another recent issue that i think has gone away but I just experienced again where the VAE would be taking forever to process like 20 minutes.

I will try the disable malloc command

comfy-aimdo 0.2.7 (and 0.2.8) should fix the long stream off errors and a certain crash that follows. You may still get that "could not account free" error message but it should only happen once and the system stays responsive. LMK.

Idk if it's the same issues, but yeah it just happened to me too (comfy-aimdo 0.2.8) after a few runs of LTX 2.3.

I got a similar message, and it still says the prompt executed and the system is still working.

But the output preview video isn’t updated in the UI, even though the file is saved successfully.

comfy-aimdo 0.2.7 (and 0.2.8) should fix the long stream off errors and a certain crash that follows. You may still get that "could not account free" error message but it should only happen once and the system stays responsive. LMK.

Ok, might take a day or two of testing but I will, did a few videos after this update and no issues but given it has been intermittent I will see over the weekend, I hope that's it.

Thanks.

Great to hear and thanks for the details. Between this and another detailed report of the same we got there.

There is a specific fix for this in comfy-aimdo 0.2.7. Please update.

Same issue. I initially had an issue with CUDA as described in another topic here but changed to a different workflow and that resolved that.
Now it keeps getting stuck on 32% on VAE and then crashing. Last attempt even crashed my computer completely.

Working with Nvidia GeForce RTX 4070 SUPER
Comfy 0.16.4 Release

ComfyUI worked perfectly fine for me before the update, now using it crashes my PC...

Hey, I have isolated reports of this but I have no reproducer. Basically the more data you can send or variables you can isolate the better and we can get a fix. Can I get your Cuda crash log and accompanying workflow?
