<br>
<b><u><span style='font-weight:bold'>Further Problem Description:</span></u></b><u><br>
</u>Many times you will be able to tell when the problem first started by
looking in the Application Event Viewer on all nodes for an Error message from
CallManager. This message should state that an SDL connection to one or more
nodes went OOS (out of<br>
service). <br>
<br>
Ideally the low level networking part of CallManager should alert all other
processes when the SDL link goes down. This will allow them to reestablish
their connections when the CallManager process recovers or is restarted. In
this case they are n<br>
ever notified that the service went down, so they do not attempt to recover.<o:p></o:p></span></font></p>

</span></font></u><font size=2 color=navy face="Century Gothic"><span
style='font-size:10.0pt;font-family:"Century Gothic";color:navy'>After a stop
or crash of the CallManager service on any node the connection between the
processes that monitor the database for changes and the CallManager processes
on all nodes will fail to re-establish.<br>
<br>
This results in the CFA changes being written to the database (and can be seen
in the CCMAdmin web page) but the CallManager process on each node will not be
notified that the change occured.<br>
<br>
<b><u><span style='font-weight:bold'>Workaround:</span></u></b><br>
Restarting the Database Layer Monitor service on all nodes in the cluster
should recover the connection (this is not service impacting). In extreme cases
a restart of CallManager may be necessary as well, which will be service
impacting.<br>
<br>
Note that after the connection is restored the forwarding information internal
to CM memory may be corrupted for phones that were "stuck" forwarded
during the outage. To fix this change the CallingSearchSpace for CFA under the
line that is "stuck".<br>
Update the line, then reset the devices. You can then change the CFA CSS back
to its original value and the phone should display the correct CFA information
and calls should be routed appropriately.</span></font><o:p></o:p></p>
