I have a large (360,000 features, 1.69 GB) dissolved land cover dataset feature class of just the forrest cover in the James River Watershed in a file geodatabase. I am trying to perform an inner buffer (-100m) to create a feature class of core habitat. I have selected and created a new layer from this that excludes any feature with shape length less than 100m. I have projected it to the correct coordinate system and repaired geometry. However, the buffer still runs up to 100%, goes back to 0%, and then fails. I am using arcgis pro to take advantage of the 64-bit geoprocessing capability of my computer, which also has 12 GB RAM and 3GHz CPU, though I have also tried to do it in ArcMap 10.4.1. All the failed output files are 5.33 KB and task manager shows that disk usage/activity ceases once it hits 100%. The output is to the file geodatabase and the parameters are Side Type: Full.... Method: Planar.... and No Dissolve.... -100 meters. Any advice would be immensely helpful as I have been trying to get this to work for over a week.

I am not exactly sure how to partition data like that, how would that work?

I'm not exactly sure how I would be able to stay in raster world. I am trying to calculate core habitat so I need to dissolve by land cover type at some point and I am not sure I can get there by raster.

So does it seem like it would be best to just abandon the dissolve at 87%?

Additionally I am on a bit of a time deadline and running almost any geoprocessing tool, even just a check geometry, will likely take an hour at the very least, so a solution with the minimal number of steps would really be optimal, but I have been working on this so long that I will try anything at this point really.

I can not do any tiling unfortunately my boss says that it will will create way too much overlap between polygons as it tries to smooth the edges. with this type of work, I need to keep the hard boundaries on the pixels so they don't overlap. The model that I used to get the shapefiles in attatched here as an image. When I did the merge the output was a feature class in a file geodatabase so that should not be an issue. I am not entirely sure how to go about doing this partitioning. Should I just give up on the dissolve at 87% and not waste my time?

Only other thing I can think of it to try multi part but I feel like that would mess with the lines especially with such high-res data

I have taken a large mosaic land cover dataset for the James River Watershed and manipulated it through iterate, clip, and raster to polygon then merging all the resulting shapefiles into a file geodatabase. The resulting merged file is quite large, 8GB and 22 million features. I tried to run the dissolve with ArcMap 10.4.1 but received invalid topology or topoengine errors, sometimes with (out of memory), even though I am running a pc with 12GB RAM. I am trying to run it on ArcGIS Pro since that automatically utilizes my computers 64-bit geoprocessing capability and it worked well for a while, getting up to 87% in about 12 hours but it has been stuck at 87 for the past 8 hours. I really do not want to cancel and have all this time wasted. Any recommendations?
