19826 - Communication Agent Connection Congested
- Alarm Group:
- CAF
- Description:
- This alarm indicates
Communication Agent is experiencing
congestion in communication between two
servers
and this can be caused by a
server
becoming overloaded or by network problems between two
servers.
- Severity:
- Major
- Instance:
- N/A
- HA Score:
- Normal
- Auto Clear Seconds:
- 0 (zero)
- OID:
- cAFConnCongestedNotify
- Cause:
-
- A connection
becomes congested, that is congestion level (CL) increases from ConnCL0 to
either ConnCL1, ConnCL2, or ConnCL3. If a connection becomes congested, and
there is another congested connection, then update the connection count and
re-assert the alarm.
- A connection
becomes uncongested, that is congestion level (CL) decreases to ConnCL0, and
there is another congested connection. Update the connection count and
re-assert the alarm.
Overload can be due to:
- TCP connection has
higher latency or error rate, then connection is getting into congestion state
- Far-end server is
receiving traffic at higher rate (may be from other servers). This triggers
ComAgent congestion on far-end side.
- Application process
CPU on far-end is above normal.
- Diagnostic Information:
- N/A.
Recovery:
-
Navigate to
to find additional information for the alarm
by locating the row with a sequence number that matches the active alarm
sequence number and viewing the Additional Info column.
-
Navigate to
to check the event history logs for
additional Communication Agent events or alarms from this MP
server.
-
Navigate to
to determine which
connections on the
server
have abnormal status.
-
If the Remote MP Overload Level (OL) > 0 then
determine why the remote
server
is congested.
-
Verify the remote
server
is not under maintenance.
-
Examine the remote's CPU utilization.
