Error description

  • There is a memory leak of SAF credentials' artifacts when
    stressing a z/OS Liberty Profile server.  The server might
    fail due to a Java Virtual Machine heap exhaustion.
    
    An analysis of the heap dump shows the
    com.ibm.ws.security.credentials.saf.internal.SAFCredTokenMap
    as the memory leak suspect, with a large portion of the heap
    used by it.
