  • Closed as program error.

Error description

  • When an Integration Server is configured to use embedded
listener for SOAP and HTTP nodes, high CPU utilization is
observed even when message flows are idle.  This is more evident
when message flows are deployed with high number of additional
instances and configured to start additional instances when flow
starts.

When an Integration Server is configured to use embedded

observed even when message flows are idle.  This is more evident
when message flows are deployed with high number of additional
instances and they are configured to 'start additional instances
when flow starts'.
