Buffer Cache Page doesn't load in SQL Server agent. (4245003)

When trying to access the DBSS agent "Buffer Cache" dashboard the following error occur:

"An error occurred while trying to retrieve data to this screen. If this issue persists, contact Quest Support."

In the agent log files an execution timeout can be found.

"Error in getBufferCacheList: RemoteException occurred in server thread; nested exception is: com.quest.qsi.fason.framework.connections.common.exceptions.JDBCServerException: Failed to run Buffer_Cache_List collection."

Increase the collection timeout. By default the Buffer Cache collection query timeout should be 300 seconds.

1. Navigate to Administration | Agents | Agent Status

3. Click on Edit and then Edit Properties in the menu
4. Click on the link to modify the private properties for the agent
5. Scroll down the Collection Details area
6. Click the Edit button next to On demand collection details
7. Add the BUFFER_CACHE_LIST collection if it already present
8. Increase the query timeout to 600 seconds
9. Click the Save button
10. Navigate back to Agent Status (Administration | Agents | Agent Status or by clicking the Agent Status link in the top right corner of the page)
11. Click on the Deactivate button
