TCP/IP-based Applications Hang on Multiprocessor Systems (114541)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
- Microsoft Windows NT Advanced Server 3.1
This article was previously published under Q114541 SYMPTOMS
TCP/IP-based applications may hang on multiprocessor systems. A sniff of
the problem shows the Windows NT machine receiving and ACKing a FIN, but
never sending its corresponding FIN.
CAUSE
The TCP/IP stack does not send a disconnect indication to the application
if the packet with the FIN bit set is being processed by one processor
while a previous data packet is concurrently being processed on another
processor. This can occur when two NDIS DPCs run concurrently on the same
interface, which is possible only on multiprocessor systems.
RESOLUTION
None available at this time.
STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT
Advanced Server version 3.1. This problem has been corrected in the latest
U.S. Service Pack for Windows NT and Windows NT Advanced Server version
3.1. For information on obtaining the Service Pack, query on the following
