you seem have more 1 messagebox db deployed in master-slave configuration, why you;re seeing 2 of each job running. these jobs part of normal setup , need execute @ frequency specified.

when active/active, db split across servers? other db running alongside messagebox db (in same resource group or same node)? in experience, both dta & bam databases should not share same resources messagebox db in high volume/load environment. have @http://msdn.microsoft.com/en-us/library/bb743398(v=bts.10).aspx hints/tips on optimizing database access across biztalk databases.
