SETUP:
Two instances of ArcGIS Server 10.1 installed on two separate machines that are clustered.
ISSUE:
We have been experiencing a strange occurrence where, on one of our nodes, the Data Stores appear to be missing (both Registered Databases and Folders) in the ArcGIS Server Manager for that node and the other node shows them. If we restart ArcGIS Server on that node, we still come up with an empty list of Data Stores. It has no ill effect on our services but it does stop us from publishing services to that node as they do not exist. However, if I try to re-add them, I get a message telling me that they already exist. I get errors like this in the Logs:
ERROR MESSAGE:
SEVERE-Apr 4, 2014 9:03:25 AM-Unable to find the data source 'com.esri.arcgis.discovery.admin.dataspace.DataItemFilter@36e5713e'.-Admin
SELF HEALING:
The strangest thing about it is that after a few days of it not showing up, it suddenly appears.
ANY HELP OUT THERE:
Has anyone else experienced this before and what did you do to fix it other than waiting until it fixes itself?
