Listener is not coming up with error TNS-12560 TNS-12557 TNS-00527 NL-08014

 Hi All,

Today one of production system we got below error while starting listener.

TNS-12557: TNS:protocol adapter not loadable
 TNS-12560: TNS:protocol adapter error
  TNS-00527: Protocol Adapter not loadable
    NL-08014: Failed to initialize Diagnosability framework, falling back to old network tracing/logging
     NL-08002: Diagnosability  context creation failed

Found issue related to permission on directory /var/tmp

Where oracle user doesn't have permission to write. After permission issue fixed listener came up fine.

Thanks,
