显示全部CauseThis error typically indicates a timing condition in long-running reports. Reports that run for more than 7 seconds enter an "asynchronous communication" mode. In this mode, the session sends periodic "wait()" requests to retrieve the data. If this request isn't received for over 30 seconds (the default async timeout) due to delays in the architecture, the dispatcher closes the session. This error is generated when the dispatcher then receives the "wait" request for the closed session.
Resolving the problemPossible environmental causes and solutions of this error:
Ensure that the minimum hardware requirements for Cognos 8 have been met.
Ensure that settings for a local firewall are not interfering with Cognos 8. Either disable the local firewall, or if that is not an option, modify the firewall settings for the Cognos 8 ports.
Ensure that multiple browsers (more then 2) aren't being used on the workstation, as this may interfere with the communications.
