    as well as APM, are configured on a virtual server, the ASM policy is configured with Session Awareness,
    and the Use APM Username and Session ID option is enabled, undisclosed requests can cause the bd process
    to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated
