Out of Memory Error Recovery?
« on: October 22, 2016, 04:02:22 PM »
I was creating the Dense Point Cloud, it was over 90% finished after running for over 36 hours.
Here are the last few lines from the log file:

There is a also new pagefile.sys file that's 72 Gigabytes.

Is there any way to recover the work that's already been done?  Otherwise, any idea how to prevent this error in the future?

Here's my system:
Windows 10, 64 bit
Intel Core i7-2600K
24 GB RAM
GeForce GTX 560 Ti

Hello B_Free42,

Please check if the depth maps has been stored in the project (can be found in the chunk contents of the Workspace pane).

Unfortunately, it's not possible to recover the data from the pagefile.
Best regards,

It looks like the Depth Maps are there. 381 of them.

I just tried to save the file, the dialog box came up saying it was saving but after several minutes the progress bar never moved. I tried to cancel the operation but it wouldn't cancel. Eventually I had to force close the program and all the depth maps are gone. Any idea what might have caused the original error or what I can do to avoid this out of memory error in the future?

The project consists of 430 tif files, 6000 x 4000 pixels each.
