FIX: Forefront UAG 2010 SP2 may stop serving client requests

Symptoms

Microsoft Forefront Unified Access Gateway (UAG) 2010 Service Pack 2 (SP2) may stop serving client requests and seem to stop responding. However, this condition may recover after about 10 minutes.

This problem may occur when you use a secure sockets layer (SSL) VPN application. As the number of client connections increases, this problem is more likely to occur.
