SYMPTOMS
A Microsoft News Server push newsfeed may back up from a master to a slave news server.



CAUSE
A stuck TCP session prevents articles from being pushed from the master to the slave. This causes the feed queue to back up.

When the final write to a file completes that should remove the server from the flow control state, it issues a read and then marks the state as no longer in flow control. The problem is that the read completed before the thread issuing the read marked the state as no longer in the flow control state. The result is that no more reads are issued and the session is dead.



RESOLUTION
Obtain the following fix or wait for the next Windows NT service pack.

This fix should have the following timestamp: 01/27/98 02:20p               714,000 nntpsvc.dll (Alpha)

01/27/98 02:19p               469,072 nntpsvc.dll (Intel) NOTE: This hotfix supersedes the fix referred to in the following article in the Microsoft Knowledge Base:

176672 INS: Feed Sessions Dropped Due to Failure Opening Articles

With this hotfix applied, the thread issuing the read marks the read as removing the session from flow control. Therefore, regardless of the timing of the read completion, the session is always removed from flow control and re-issues new reads.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Commercial Internet System 1.0.

A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
