CauseThis issue is due to corrupted discovery_cache.map file.
ResolutionFollow the below steps to start rsa-sms service.
  1. Login to Node-0 (NwServer) putty with root credentials.
  2. Rename the old discover discovery_cache.map file as different name.
    sample commands:
    cd /opt/rsa/sms/
    mv discovery_cache.map old_discovery_cache.map_old

     
  3. Start rsa-sms service using systemctl start rsa-sms.service command.
  4. Verify rsa-sms service status using systemctl status rsa-sms.service command.
  5. Also, this creates new /opt/rsa/sms/discovery_cache.map automatically.
