Constantly waiting for intermittent spinning 'busy' wheel cursor. Why? Can I eliminate it?

Intermittently, every 30 to 60 seconds or so, I have to wait for the spinning ‘busy’ wheel of death cursor, and it is super annoying! I can’t get any work done because I’m constantly waiting for Blender to finish some mysterious background task before it will let me do anything. It doesn’t seem to have any relation to what I’m doing. I could be doing nothing but moving around in the viewport. If I try to do anything while that’s happening, the screen goes white. It tells me Blender is not responding, which I can see. It’s not because of what I’m doing at the time. It’s not like I asked Blender to do something really difficult and it’s working on it, although that happens too.

I thought maybe it was my auto-save setting, that it was busy saving my scene, but I turned that off. No effect. I’m still presented with the spinning circle for some unknown reason. I can’t seem to trigger it with any action. It just appears to be a random occurrence.

Does this happen to everyone? Is it my computer specs? I have an HP Z600 Workstation with 2 Xeon processors. I don’t think it’s the GPU because I never hear it’s fans revving up.

I would appreciate any insight or help anyone can give me on this.
Thanks!

Autosave would have been my first guess too…

Are you tweaking shaders? Shader compilation time is pretty intense on the recent blender versions.

Any other programs running?

does the task manager show any other tasks?

Any addons?

Any network use? There’s been some unsecure blender python scripts running around lately, and they might be phoning home…

Thanks for the response! I opened up task manager to see if I could see anything changing. I couldn’t. I had Media Player open playing some music. I can’t see what would cause it.

Does it happen with all scenes? does it freeze up just rotating around the default cube?

Sounds like your PC is running slow, could you provide the specs of it.
Also does it happen on every Blender version or only some?

silly question: did you restart your computer and only start Blender → does it still happen?

That might help, I forgot to mention that in my post.

Thanks. I will try some different things to try and find out what’s causing this. It doesn’t seem to be related to anything I’m doing at the time, and I don’t think what I’m working on is anything too heavy.

Normally, when I read 2 Xeon processors, I’m thinking that’s a beefy computer. One that shouldn’t be brought to it’s knees by running Blender.

@Spaceboy64 I have experienced this problem before. For me, when this happens, the HDD led is on constantly, indicating the system is using the hard-drive constantly. Checking the Task Manager, I found something called ‘DDE Server’ running that was using a lot of the system resources.

Ending that task (not recommended) or restarting the computer fixes the problem. I looked it up and DDE Server is for transferring data between programs. I’m not sure exactly what it does, but it appears to get stuck in some kind of endless loop, hogging up all your computer resources.

For me, it’s rare that it happens, but when it does, I restart the system.

Thanks. I have found that there are a LOT of background tasks running for things I’m not even using! Adobe is a major one. Creative Cloud, Acrobat, Adobe Content Synchronizer, AcroCEF, Adobe Crash Processor, all active even though I’m not using Creative Cloud at all right now. Lots of things like that. I’ll try closing those things, but it really seems like it’s something Blender is doing.
Thanks!

Adobe loves installing dozens of spammy malware services that run nonstop :unamused:

Yes, lots of tasks running, but are they using your CPU’s? In the task manager, look to the CPU column. If a task is using 0% of the CPU, then it’s not really running, it’s just some code stored in memory.

Does this happen every time you use Blender, or only part of the time?

If it happens every time you use Blender, then probably something about Blender. If it happens only sometimes when you use Blender, then it’s probably one of those background tasks. Consult the Task Manager and look at the CPU column.

Thanks, that’s sort of what I was thinking. It doesn’t seem like my computer is being overly taxed by anything. I looked at the task manager and I found when the wait cursor pops up, Blender jumps to the top of the list. It’s definitely Blender causing the wait. I decided to start a new project and append just the part of the model that I’m working on. The problem isn’t happening anymore, which means there’s something in that file that’s causing the problem. I don’t know what it is. I didn’t think there was anything that complex about the scene. I will continue working on it bit by bit and append parts until the problem returns.

Also, I noticed that when I render, Blender doesn’t stop responding like it was doing before.

Thanks!
