Search query critical error -Event 60 (SharePoint Server 2010)

Alert Name: Search query critical error
Event ID: 60
Summary: In scenarios where a query component has no mirror and lacks high-availability, or all query components in a query group fail, it is possible that query results will not be served for a portion of the index.
Symptoms: Microsoft SharePoint Server 2010 experiences the following symptoms when serving queries:
 Query latency increases or queries fail.
 This event appears in the event log: Event ID: 60 Description: Cannot take the last query component out of rotation. Check previous event logs to determine cause. Propagation may be necessary. <data>
The event details identifies the query component as <GUID>-<Query Component number>, for example baebc6d3-4a2e-4584-9ff7-ad8866debe92-query-30. To identify the query component, use the second part, query-30.
Cause: A query component has been taken out of rotation due to the reason present in the previous search event's error message.
Resolution: Restart the search service
1. Stop and restart the Microsoft Search Server 2010 service (OSearch).
2. Open a Command Prompt window and type net stop osearch14 to stop the search service. Type net start osearch14 to restart the search service.

If failure persists, add a new query component as a mirror in the same query group as the failed query component.
Resolution: Add a new query component
1. On the SharePoint Central Administration Web site, click General Application Settings and in the Search section click Farm-wide Search Dashboard.
2. In the Search Service Applications section, from the drop-down list select the search application that generated the event, and then click Modify Topology.
3. On the Topology for Search Service Application page, click the failed query component in the topology list, and then select Add Mirror from the component’s drop-list.
4. In the Add mirror query component dialog box, select the query server and associated metadata database for the new query component, and then click OK.
5. Click Apply Topology Changes. The changes are processed for the search application and the index is copied from the failed query component to the new query component.
6. Click the failed query component and click Delete.
7. The topology removes the index from the failed query component and deletes the component.
