When the ArcGIS Server system directory is located on a shared folder, MSD files are generated in the temporary directory and are not automatically removed.

解决办法

1.     Stop the ArcGIS Server and manually delete the MSD files from the service account user's temporary directory: https://support.esri.com/en-us/knowledge-base/how-to-delete-arcgis-enterprise-temporary-files-000028693

a.     Note: this may have to be done on a regular basis due to MSD files consistently being created after deletion.

2.     For a single-machine ArcGIS Server site, configure the ArcGIS Server system directory to use a local folder (e.g. C:\arcgisserver\directories\arcgissystem).

a.     Note: When the ArcGIS Server system directory uses a local folder, no MSD files are created in the service account user’s local temp folder.
