APAR status

  • Closed as program error.

Error description

  • The user observed exhausted JSON Keys not cleaning up as per
XML Names status provider and "system" "notice" logs.
In normal circumstances this user's setup consumed JSON Keys
regularly but those also cleaning up as defined in Throttle
Settings > XML Names and JSON Keys Warn At.
Analysing the Internal State QRef section uncovered a QRef leak
related to a certain stylesheet - and this QRef leak blocked
JSON Keys (as well as XML Names) cleanup.
The troubled stylesheet contained a <xsl:message> construct
with "dp:variable('var://service/URL-in')" which broke XML
Names and JSON Keys cleanup in case of a bad URL.

Local fix

  • Restart DataPower.

Problem summary

  • The fix will catch any non-UTF8 characters in the message and
suppress the log message.

Problem conclusion

  • The fix will be in 2018.4.1.14 and 10.0.1.1

Temporary fix
