I know two situations that might result in this exception: realy heavy load on Tamino (which is probably not what you have) and: Tamino is running out of sessions. You could try the following: open Tamino Manager and increase the number of “XML maximum sessions” (under Databases/yourDatabas/Properties/XML). This is just a guess, but I’d like to see if helps …
