I'm encountering a very peculiar bug in ArcMap 10.5. I have an mxd I created as part of a large project, and when I attempt to save edits to a feature class from the project's file geodatabase (~38 GB) ArcMap freezes every time. Initially I suspected that either my mxd or geodatabase had been corrupted, but I can successfully save edits to shapefiles from different directories in the same mxd AND save edits to feature classes from the same geodatabase in different mxd's. Perhaps it's something about the particular combination of layers that are added to the dataframe? I really don't know. Everything is in the same projection and I haven't encountered errors running any other tools or processes. Without success, I've tried:
- Clearing the geoprocessing history and image cache
- Compacting the geodatabase in ArcCatalog
- Running MXD Doctor on the map file
- Copying the geodatabase and changing the data source to the backup
- Copying the data frame from the original mxd to a new map and editing in that window
- Whitelisting the directory the geodatabase is stored in in my antivirus (Windows Defender)
Edit: The File Geodatabase is local, not in a network location. No other programs are trying to access the files simultaneously. In reference to a few of the other questions, the number of features in the layers being updated varies-- the problem is not confined to any particular feature class or layer. It happens when trying to save edits to any layer in the geodatabase unless I edit them in a new map with only one or a small subset of feature classes added.
Edit 2: Yes, the geodatabase contains a number of large rasters and shapefiles that cover an entire state. But it's not even close to the storage limit by total file size or number or files, so I'm not sure that would be the issue. I haven't had any issues editing until a day ago. I tried compacting the geodatabase this morning with no success. I'll give compression a whirl and see if that helps.
