CTGKS0011E TLS Listener went down.

  Explanation The TLS Listener
that IBM® Security Guardium® Key Lifecycle Manager server provides has failed, possibly
because the TLS socket timed out, or because a port conflict occurred. 

  System action
   The operation fails.

  Administrator response
To restart the TLS Listener, you must restart the IBM Security Guardium Key Lifecycle Manager server. You might need to change the value of the
port or the timeout interval. Then, try the operation again. If the TLS socket continues to time out
again, or a port conflict continues, you might need to contact IBM Support.
