IT33375: MEMORY GROWTH MIGHT OCCUR DURING PAYLOAD LOGGING

Fix packs for DataPower Gateway version 2018.4.1
Fix packs for DataPower Gateway version 10.0.x

APAR status

• Closed as program error.

Error description

• There is a situation that involves APIC and DataPower when
  logging payload data from success/error events. The specific
  use case is when DataPower is logging the payload from either a
  request/response body & that payload size's remaining size is
  less than zero.
  The way to tell if the remaining size is less
  than zero is to compare the payload size with the Max Record
  size in the API Analytics endpoint.
  

Local fix

• Increase the Max Record size so that value does not dip below
  zero or disable the API payload logging entirely.
  

Problem summary

• When using DataPower API Gateway, if the log type is set as
  payload, and the transaction includes either request body or
  response body, and the log file size is approaching the Max
  Record Size, then it will cause memory leak in Analytics
  Endpoint.
  

Problem conclusion

• Fix is available in 2018.4.1.13 and 10.0.0.1

Temporary fix

• Increase the Max Record Size, or disable the API paload logging.
