I recently re-imaged a PC to Windows 10 x64 Enterprise Edition. After re-imaging, I installed ArcGIS Pro 2.0.1 and no other ArcGIS Desktop components (ArcMap, ArcCatalog, etc....). Sometime after a week or so of installing Pro, I noticed thousands and thousands of *_gdal.sqlite files in my %TEMP% folder.
I cleaned up my temp files and just figured it was tied to the install. Within 48 hours, I had ~2,500 files back, and I never even launched ArcGIS Pro in that 48 hours! I tracked the files down to the ArcGISIndexingServer.exe process. I know there have been some memory-usage issues with that process, FAQ: Why does the ArcGISIndexingServer.exe use a high amount of computer memory? , but I haven't seen others talking about this issues.
The fact that this is a newly re-imaged machine with a clean install of ArcGIS Pro is what has me scratching my head. My machine is about as default as it ever will be, so I want to understand why either the process needs to create so many temp files or why it doesn't clean up after itself.
If others check their %TEMP% directories, how many *_gdal.sqlite files are there? If there are some, how many have been generated in the past day or so?
