I started getting a hang after my 10.9.5 update. It really only has happened when I'm driving the crap out of it. bouncing around on a 5 minute timeline with 200+ edits of 5k source files and a decent amount of NR on each node. I can check the heat and it appears fine. I tried rolling the cuda driver back and using the last version of Resolve, but the problem remains. I'm not very good at troubleshooting. I do get an error report that's 100+ pages long and I have no idea how to interpret. Any guidance would be appreciated.

Thanks,

Use the 'CaptureLogs' app that Resolve installs to grab a meaningful log, after the force quit/crash and prior to restarting Resolve. Post a link to the zip here and details of your system.

Thanks for the response and I'll get a log this afternoon or tomorrow.

I do think I realize what the problem is. maybe. The system seems to be running out of RAM. The last time it happened I noticed that Free RAM was down to 1 gig. Out of 32. I installed a program called icleanmemory and when clicked to optimize it freed up about 27gigs and everything was smooth. Today is my first real test on a job. So far it's gone from 3 gigs used on boot to nearly 19 after conforming a 5 min timeline and doing some color. I'm assuming this is an OS issue. Possibly reinstall the 10.9.5 update?

I'll get the log before I speculate more.

Thanks again,

Hi Peter,

I apologize for the delay, here's a link to my log:

I'm on a Hackintosh on 10.9.5. Been running without issue for over 6 months and this is the only program that I've seen hang like this. I have a GTX 780 6GB. I have been using a lot more NR on a few Red jobs and I know it taxes the system in every way possible and this is when it hangs. Like i said before, I've seen my 32gbs of RAM show as little as 1gb available while bouncing around on a R3D timeline with a decent amount of NR.

Thanks for looking at this,

jb

What you've linked to is a Mac system log, not the requested output from the Resolve CaptureLogs app, which will be in the form of a .tgz file placed on your desktop.

Capture logs is in /Library/Application Support/Blackmagic Design/DaVinci Resolve. Double click it to run it. Run it after a Resolve crash and before restarting Resolve.

I think I got it:

Thanks!

Nothing jumps out at us with the log.

It would be helpful if you can export the project (Resolve File menu, Export Project) and provide a link to the .drp file. And any info you can provide with the project as far as what it takes to make Resolve hang after loading the project.

I can repeat the issue when I conform from 5k R3D files on an HD timeline, each shot with NR, smart cache on...When I re-enter the session and begin to bounce around I see the cache feature attempting to cache the shot I'm on, at this point it's caching source and the NR. if I bounce around to a few shots while it's trying to cache it hangs. Basically the picture stops moving, I can continue to bounce around the timeline and I can save it and exit, I just need to force close to open it again and I get the hang report. Also, all caching ceases during the hang.

Same issue on 10.10.4


Only have had it happen with R3D files using Smart Cache and using NR at the same time and while bouncing around on a timeline. Always able to save the project and a restart of resolve solves it. Get a little colorwheel spin and then the picture simply freezes but I can still navigate around.

Can't get it to happen without using the Temporal NR.

As I said it has continued into Yosemite. I think I may have found the issue:

Every time it hangs the process "QT Decoder" in the Activity Monitor turns red and reads that it is unresponsive. I thought it might of been my caching to pro res, since it's the only thing I'm doing in the QT world. Source files are 5k R3D. Even after switching my render cache to DNX files I still get the QT Decoder unresponsive error in the Activity Monitor. and a hang of course.

This has never happened during any render of any length to Prores or any other file type. It only happens when working with R3D files with a lot of NR using Smart Cache.

I'm on:
10.10.4
2x GTX 780 6GB
64GB of DDR3 1866

Thoughts?

My first thought is that it's normal for the QTDecoder app to be red and reporting (Not Responding) in Activity Monitor a few seconds after Resolve is launched, under Mavericks and Yosemite. This is not indicative of a problem. This has been the case since Mavericks was introduced. I don't know WHY it does this, I only know that QTDecoder is normally working fine, since Activity Monitor always shows it in the un-responding mode.

It might help if you ran CaptureLogs after you force quit Resolve, and post/link to the .tgz file it generates.

Hi Dwaine

I have a similar problem my log is at the link attached

Jeff, can you provide more detail?

Can you also export your Come Get Her project and link to the .drp file?

And while you are at it, a copy of your Mac System Report in an .spx file could be helpful. Or at least details on what GPU and CUDA driver you are using.

GPU driver is 346.01.03f01
CUDA driver 7.0.52.

Maybe something with smart cache debayering r3d files and caching nr at the same time? I'm going to look at dropping down from premium debayer.

cheers
