Error description
Using the WSDL-cache-policy to compile locally stored WSDL files, the resulting QRef entries might not be returned which results in memory growth. This behavior happens in firmware versions 6.0.0.0 and later.
Local fix
Scenario for cause of growing QRef entries: 1) The WSDLs have WSPolicy embedded inside the WSDL. 2) The WSDLs are all local. 3) The WS Proxy has wsdl-cache-policy & matching is set to "*" Number 3 is where the problem happens. Every 30 seconds, the WS Proxy is recompiling the locally stored WSDLs and recreating all those WSPolicy objects. To work around this issue, make one of the following suggested changes: 1) Either turn off the unnecessary WSDL cache, or change the match expression to something more meaningful, such as "http://*" and increase the TTL. 2) Use the WSDL Status->refresh action to recompile the WSDLs which are stored locally. (Usage: wsdl-refresh <WSGateway> <WSDL>)
Problem summary
Affected is the use of WSDLs (in WSP or elsewhere). WSPolicy documents referenced by <wsp:PolicyReference> are not released during WSDL compilation causing memory growth. This causes trouble especially in case of aggressive wsdl-cache-policy settings leading to frequent WSDL recompilations.
Problem conclusion
Fix is available in 6.0.0.8, 6.0.1.4 and 7.0.0.0. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
