Clicking on the option to load a map service in ArcMap from the ArcGIS Rest API fails with the error "500" when using a Network File System (NFS) shared directory for arcgisoutput.
This issue is not reproducible in the current release of the software. If you are encountering this issue, please contact Esri Technical Support (for customers in the United States) or your Esri distributor (for customers outside the United States) to resolve this issue.
解决办法
1. Upgrade to ArcGIS 10.1.2. Use a local path for arcgisoutput or Windows shared directory.
