APAR status

  • Closed as program error.

Error description

  • An OutOfMemory may occur when the WebContainer custom property
    com.ibm.ws.webcontainer.disablestaticmappingcache is not read
    in by some application.
    

Local fix

  • One workaround is to stop and restart ALL the application.

    * PROBLEM DESCRIPTION: An OutOfMemory exception may occur      *
    *                      during application runtime even         *

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A race condition might cause the WebContainer custom property
    not to be picked up by some applications during the server
    startup.  This can cause a memory shortage for those
    applications which serve a large amount of static content.
    

Problem conclusion

  • The WebContainer code was modified to provide an alternative
    way to set the custom property
    
    com.ibm.ws.webcontainer.disablestaticmappingcache = *
    
    via the server's JVM.
    
    The fix for this APAR is currently targeted for inclusion in
    fixpacks 7.0.0.41
