The folding container is formed from a single seamless sheet of liquid impervious material to form a container for liquids or bulk goods as desired. The sheet forming the container is folded along fixed fold lines, i.e., folds that remain permanently in place to define the various panels of the container, and hinge folds, i.e., folds along which the side and bottom panels may be spread to open the container for use or closed to fold the container for compact storage. The side and bottom panels fold inwardly between the front and rear panels of the container for storage, thus providing an even more compact configuration. The front, rear, and both side panels are configured as trapezoids, with their bases wider than their upper edges. This provides greater stability for the container when filled, due to the lower center of gravity of the mass contained therein and the wider base.

A method, apparatus and computer instructions are provided to improve the push / pull workload management model with intelligent routing to effectively collect data from systems that consist of dynamic sub-systems. The invention improves the push / pull model of the referenced invention with intelligent request routing to solve the above problem. An API is exposed in the workload manager enabling its request router to decline requests to route to idle sub-systems. This allows the monitoring agent to avoid sending a pull request to an idle sub-system. Each sub-system will push the data to the agent as it enters the idle state. The agent caches the data it receives from idle sub-systems and combines it with data it pulls from active and stopped sub-systems.
