IT39341: SLOW DATAFLOWENGINE MEMORY GROWTH WITH RESOURCE STATISTICS ENABLED

APAR status

• Closed as program error.

Error description

• Resource statistics are collected to record performance and
  operating details of resources that are used by integration
  servers. Since IBM App Connect Enterprise Version 11.0.0.8, the
  publication of resource statistics is enabled by default for
  newly created integration servers. It has been seen that with
  resource statistics enabled, the process size of integration
  servers (DataFlowEngine processes) very slowly grows over time.
  

Local fix

• Disable resource statistics by editing the node.conf.yaml or
  server.conf.yaml file to set the reportingOn property to false.

  PROBLEM DESCRIPTION:
  Resource statistics are collected to record performance and
  operating details of resources that are used by integration
  servers. Since IBM App Connect Enterprise Version 11.0.0.8, the
  publication of resource statistics is enabled by default for
  newly created integration servers. It has been seen that with
  resource statistics enabled, the process size of integration
  servers (DataFlowEngine processes) very slowly grows over time.
  A new JNI local reference is being created before every
  collection and publication of resource statistics, which occurs
  every 20 seconds when enabled, but the local reference is not
  being deleted afterwards.
  

Problem conclusion

• The product has been updated so that it now deletes the JNI
  local reference after every publication of resource statistics.
