This issue impacts site performance. There might be a high CPU in the Reference Data database, increased latency due to the large volume of transmitted data, writing of redundant data (for example, User Agents, Geo IP, Location, or Devices Information) to the RefData database, or even a site shutdown. Exceptions arise as a result of insufficient cache size that leads to additional load.
