My understanding after talking to Tech Support is:
- these xml files are written because of a Project setting: "Generate operational metadata".
- the xml files are stored under .../InformationServer/ASBNode/conf/etc/XmlFiles
In our case, the problem was caused by file permissions (the job was previously run by a userid that had a different primary group... nobody else had write permissions). So the fix was to ask the sysadmin to change the group ownership on those xml files.
I believe the problem could also be avoided by changing the Project setting to "share metadata when importing from connectors".
Old post, I know, but would just like to say that the same warning was removed immediately for us by doing what Gazelle suggested.
Deselecting "Generate operational metadata" only was our solution.
Also, I wonder how is it that this problem started happening all of a sudden without obvious reason? We had the metadata generated for this project for quite some time, and there were no complaints.
The /XmlFiles and its folders have got the full privileges for the owner.
