ErrorChangeNotifyClientBlock
A change notification client is busy (blocked). If the change notification client continues to be blocked
for 10 minutes, the system automatically clears the block and change notification should resume
successfully. Changes made to the database are not being consumed by one of the recipients. This does
not always represent an issue. However, if the change notification client continues to be blocked for 10
minutes, the system automatically clears the block for all clients except the blocked one, which means
that change notifications should resume successfully for all other clients. To clear the blocked client, you
must restart the server.

Severity
Critical (2)
Recommended Action
At the command line interface (CLI) on the database server, execute the following command:
show tech notify
The CLI command output will provide information about the block. Use Cisco Unified Serviceability to
restart the server that was indicated in the alarm. You may also want to gather traces to examine them
for anomalous activity during the time that client was blocked. In Cisco Unified Serviceability, enable
Detailed level traces in the Trace Configuration window for the Cisco Database Layer Monitor service.
Also, use RTMT to look for a change that may have occurred around the time of the alarm.
