XADM: Continuous Attempts to Publish Free/Busy Information (152902)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q152902 SYMPTOMS
In Microsoft Exchange, a countdown is set whenever the server schedule
receives an unknown or Free/Busy notification. When the countdown reaches
zero, the Free/Busy information is published.
If the publish fails, the countdown is reset to the same wait. However, if
the Public Folder server is gone, the time-out to determine this exceeds
the countdown and the idle engine calls back for Microsoft Exchange to
retry nearly immediately.
WORKAROUND
Use a doubling retry time-out, maximum of 30 minutes. After each failure,
the time to the next attempt doubles until the wait peaks at once every 30
minutes. Once the Free/Busy information is published, the time-out restores
to 30 seconds.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Microsoft Exchange Server 4.0
U.S. Service Pack 2. For information on obtaining the service pack, query
on the following word in the Microsoft Knowledge Base (without the spaces):
MORE INFORMATION
Free/Busy publish retry rate after failure tended to be too high;
therefore, almost all of the Microsoft Exchange Server time was spent in
Free/Busy publish attempts and not giving any time to the user.
