Event InformationAssociations are paths that are opened to other systems. Each association is contained within a connection and is used to transfer messages to a system. You may have multiple associations in each connection. Use Performance Monitor to determine if a particular item is taking up too much memory. To allocate more memory, close any nonessential applications. You may also increase your system's physical or virtual memory. Verify that there is enough disk space for the paging file to grow.
