Understanding memory usage in DataFlowEngine

Understanding memory usage in DataFlowEngine process is important in IBM Integration bus when we have memory issues in Integration Server or Execution group. There is a common question from customers asking why IIB is consuming lot of memory where Execution groups get hung or there is no memory available to process further requests.

There is Support link from IBM which clearly mentions about on how Dataflowengine memory usage works,

Link for reference: http://www-01.ibm.com/support/docview.wss?uid=swg21106136

A regular monitoring of DFE processes in Linux environment along with Application monitoring in IIB Console is a best step to identify the root cause of the memory issues.
