FIX: RPCSS Does Not Release TCP Connections (297689)

SYMPTOMS

Under heavy load, RPCSS does not release Transmission Control Protocol (TCP) connections between the COM+ application proxy on the client computer and the COM+ application. Even hours after both the client and server processes shut down, the TCP connections are not released.

NOTE: This problem only occurs if the application passes interface pointers between the client and the application server. If the interface pointers are not passed, this problem does not occur.

The following error description may also be logged in the Event log:

DCOM was unable to communicate with the computer <COMPUTERNAME> using any of the configured protocols

When you use Performance Monitor or Netstat to monitor TCP connections, you see that the TCP connections are not released.
