SYMPTOMS
When you use Microsoft Windows Server 2003 to implement Winsock Direct (WSD) in a fast System Area Network (SAN) environment, you may experience any one of the following WSD-related problems:
 * The network communication program stops responding when you send lots of data.
 * Data that is sent over the network is not received correctly. Data corruption may occur.
 * You receive access violation error messages in the network communication program.
 * Unexpected behavior occurs in the network communication program.



CAUSE
These problems may occur if you are using a Remote Direct Memory Access (RDMA)-capable network or the InfiniBand network architecture to enable WSD. Problems may occur because of timing issues.
