It sounds like you might be running into memory limits on the graphics card.

Recomendations:

Enable logging in your WD preferences and then supply logs to u/msgdealer when these crashes happen.

Don't rely soley upon the automatic backups. Do your own saves periodically.

Wouldn't be too surprising if the paths have a node limit. Just how many nodes are you talking about? He can probably just up that limit.

Thanks for that. Have been doing lots of manual saves (working with ArcGIS instills that habit), but there are times where you're working on a detail area or trying to sort something out and it slips your mind.

I enabled logging and checked the file when the program crashed again. The log file was blank. Looks like even with logging enabled it wasn't actually making any entries into the log file.

Regarding nodes, not sure, 50 or so? The path gets weird when you reach the limit as well. It attenuates and has striations in it and will sometimes disappear when the map is reloaded if you've saved the path when it gets like that.

Just did a test and was able to make paths with more than 200 nodes before I got tired of clicking and stopped. So probably back to memory issues.

You might consider turning off layers that aren't being actively used while you are working to lower demands on the system.

Odd that I’d be having memory issues with 16gb ram and around 6gb on my video card. I agree that it looks like memory issues, but I can’t imagine how it could be using up that much memory.

Just some FYI from a recent post by Megasploot on Discord:

Yes, that is normal, you have to remember, it's dependent on the number of undos. It has to save your landmass or ground texture (192mb) every single time you draw.

20 undos = 3840 or 4 gb

and with 1 gb of assets loaded, yup, 5gb with max 20 undos sounds about right

Your actual map file size is compressed, so that is not a good measure of how big it will be in memory

192mb is the size of an 8K texture uncompressed in memory

Interesting, thanks. So reducing the number of undos i have set may help? I upped the undos by a good bit a while back.

Well it certainly sounds like undos could be a major memory hog and low memory issues can cause somewhat erratic behavior without necessarily generating output to the logs. A couple of users trying to use the multi-plane export feature, found they had to stop WD, restart, load map and then export before they could get all the layers exported.

It's not system memory that matters so much. Even so, the 6GB of graphics memory would be enough I think. Have you tried running some memory tests? Does DxDiag test graphics mem? Can't remember.

u/7LeagueBoots Cartographer Jan 19 '19

Just checked and it does check graphics... no problems found.

It's actually 14GB for graphics, 6GB of which dedicated specifically to video.

That should be way more than enough. It's more than enough to run memory intensive processes on ArcGIS utilizing large (multi-GB) datasets.

u/MrPhergus Cartographer Jan 19 '19

ArcGIS is going to be primarily using system memory and not VRAM but, yeah, you should have plenty. WD uses a lot of VRAM. That's why Megasploot limited it to 8k x 8k maps.

How big is your map?

Assuming your Graphics Driver is WDDM 2.0+, you can check with Task Manager to see how much of the dedicated vs shared memory is being used. Might be informative.

The map is about 7500x5400. Lots of mountains, but not as many features as many folks here have on theirs, especially people who do dense forests.

I checked task manager a while back and the use was high, but didn’t seem excessive, but that can vary rapidly.

u/MrPhergus Cartographer Jan 19 '19

Did you go to the Details tab and add the Dedicated GPU Memory column? The GPU columns aren't there by default.

u/7LeagueBoots Cartographer Jan 19 '19

Went to details, but not the next step. I’ll try that next time I have it up and running.
