XFOR: INS: Server Stops Pushing Articles In a Master/Slave Push Feed (187227)
The information in this article applies to:
- Microsoft Commercial Internet System 1.0
This article was previously published under Q187227 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.
