IT36726: DATAPOWER MEMORY LEAK WHEN XSLT CALLING DP:GATEWAYSCRIPT EXTENSION FUNCTION

APAR status

• Closed as program error.

Error description

• If an XSLT calls a gatewayscript and has a null nodeset for the
  input argument, DataPower may leak memory. An empty nodeset is
  fine, its only when it is null.
  

Local fix

• If the input parameter to dp:gatewayscript is not required in
  the gateway script, you can work-around the memory leak by
  removing the input and return-error parameters so the defaults
  will be used. If you need the parameters parameter, then you
  cannot use this work-around.
  
  Syntax:  dp:gatewayscript(script, input, return-error,
  parameters)
  
  change: dp:gatewayscript(?local:///DP/PG1/someScript.js?, .,
  true())
  to:     dp:gatewayscript(?local:///DP/PG1/someScript.js?)
  

Problem summary

• DataPower might leak memory and qrefs when processing XSLT
  extension function dp:gatewayscript.
  

Problem conclusion

• Fix is available in 2018.4.1.17 and 10.0.1.4.
