For example, you may encounter this issue in the following scenario:
- You configure the computers in a domain to use Authenticated IP (AuthIP) only for IPsec and without encryption.
- In the domain, a computer sends a large volume of UDP traffic to a remote computer.
Note Windows-based computers that host the DNS Server role are an example of a workload susceptible to this memory leak, because they service UDP-formatted DNS queries from a large collection of unique clients. However, the issue can apply to any remote computer that receives sufficient UDP traffic.
Note To resolve this problem in Windows 8.1 and Windows Server 2012 R2, install update rollup 2928680 .
