Author running slow. Failed to retrieve state of intermediary node error

Hi there,

I am having a problem with the Author running very slow to the point of unusable.

The setup is 1 Author server, 1 Publish server, and 1 Web/Dispatcher.

After checking in the log, I found following error repeated throughout the log, while there is not such problem in the Publish (in the log, and access speed).

In each of this error is preceeded by Reverse Replication message.

Is there any idea what's causing the problem? Any help would be appreciated.
