When attempting to access services on an ArcGIS Image Server in ArcGIS Enterprise 11.4, crashes can occur if the server's raster function file is not available. This issue is further complicated when the problem is due to a missing or moved file, which does not provide any clues in the GIS log, even debug log level, making troubleshooting challenging. This issue affects ArcGIS Enterprise 11.4, where users may experience unexpected behavior when relying on raster function tools hosted on an Image Server.
Suggestion:
Improve the GIS log to include specific information about the raster function tool that is causing the issue, such as :the name of the missing or moved file or the location where the file was expected to be found.
