SYMPTOMS
The Sender component in Microsoft Systems Management Server (SMS) 2.0 Service Pack 5 (SP5) may experience a race condition if two Sender threads try to process the same send request (.srq file) at the same time. When this race condition occurs, you may experience one or more of the following symptoms:  An error that is similar to the following is logged in the SMS\Logs\sender.log:

Cannot create/open the remote file \\SMSServer\SMS_SITE\2_K1Q0P0.PCK, Win32 error = 32The Sender component may also mark the send request as invalid.

 The two Sender threads manage the send request and send the same data two times. The first Sender thread exits correctly, but the second thread fails. The second Sender thread exits correctly, but the first thread fails. The send request is flagged as invalid (SREQ_STATUS_INVALID).

The orphaned or invalid send requests may prevent the Scheduler component from processing fan-out routing requests (.rtr files).

You may experience these symptoms on any SMS site server in the hierarchy. However, these symptoms typically occur on the central site of a large SMS hierarchy.



CAUSE
This problem occurs because the Sender component does not synchronize the sender threads before it processes send requests.
