"An error encountered while processing the request. Please try again."

When I view the tempo report, I am getting the error as "An error encountered while processing the request. Please try again."
When I checked the logs, the error displays as "No acknowledgement from TransientTopic in 60 seconds, forcing rules cache to be cleared now."
What does that error mean?
Please provide suggestions....
