We have kind of portal application that maintains an enterprise session constantly open, periodically refreshes numerous Webi reports and embeds them to the portal. This application was perfectly working on R2. Now, we are migrating it to R3 (We have replaced old jars with new). Currently we are experiencing a very strange problem. The application is working, but after some time starts to generate com.businessobjects.rebean.wi.CommunicationException: Cannot initialize Report Engine server. (Error: RWI 00226) exception on openDocument call, After that, the attempt to refresh any webi report even via InfoView is leading to the same error. In the CMC, all WIR servers have status u201Crunningu201D, but restart of all WIR servers (simple restart, no Force Termination is needed) is resolving the problem for some time.
Is any idea how to solve the issue?
