The Managed Metadata Service or Connection is currently not available in SharePoint 2013 RRS feed

  • Question

  • We have an Internet website implemented with Sharepoint 2013. This website has been working for 10 months normally.

    Now, we are having several problems with the Managed Metadata Service for the last 3 weeks. The MMS is not available during some hours each day creating many problems.
    We have identified the next problems:
         - It's not possible modify managed navigation
         - It's not possible update SEO properties
         - It's not possible create new publishing pages
         - Multiple errors of navigation on public side of website
         - If the MMS is not available for much time, all publishing pages begin to fail

        Event viewer shows the next messages many times each day:
         - Id: 8088 Message: "The Managed Metadata Service 'Proxy Managed Metadata' is inaccessible.".
         - Id: 8313 Message: "A failure was reported when trying to invoke a service application: EndpointFailure ... Affected Endpoint: http://xxxxx/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/MetadataWebService.svc"

        When we detect these errors we recycle the Application Pool associated with the MMS and we wait for 20-25 minutes to recover the service. Unfortunately, this procedure don't solve our problems definitively, it's only a temporal solution


    We have tried to remove the MMS and create it again using the same database and this test has not been successful

    Anybody has any idea about how to solve this problem?

    Thanks

  • Check the following:

    1. Network Connection
    2. Firewall port is not blocked
    3. SQL Server Load and long running query. If this is temporary occur is there any load on this site during these hours number of concurrent users or running scheduled tasks like search Full Crawl.

  • Did you already check the permissions on the following registry key: HKLM\Software\Microsoft\office Server\15.0 As stated in a TechNet article (Account permissions and security settings in SharePoint 2013), the both users "WSS_Admin_WPG" and "WSS_WPG" need the respective permissions on this key.The permissions could be successfully added using the following PowerShell command: Initialize-SPResourceSecurity If this does not work out try to restore the Metadata DB with a backup or recreate the service with an all new DB.

  • If you choose to recreate with a new DB, export and import the termset into the new DB. https://social.technet.microsoft.com/wiki/contents/articles/5233.sharepoint-2010-import-export-termset.aspx
