SYMPTOMS
When you use the Sockdie utility with the –maxtput switch on a Microsoft Windows Server 2003 R2-based computer, the sockdie process may leak memory. Eventually, this problem may affect system performance, and a Stop error may occur.

<div class="cause_section">

CAUSE
This problem may occur after the maximum number of connections has been offloaded from the network adapter. The following events may lead to the problem:
 * The host allocates about 60 bytes of memory for each offloaded connection.
 * A new connection is established to an IP address to which an offloaded connection already exists.
 * The host then allocates memory for the connection that is to be offloaded and tries to offload the connection.

In this scenario, the attempt to offload the connection fails. This is because the network adapter has already offloaded the maximum number of connections that it can offload. The previously allocated memory block is not freed.

RESOLUTION
To resolve this problem, install the hotfix that is described in Microsoft Knowledge Base article 919948. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
