/mcpError Message %UC_CALLMANAGER-2-TimerThreadSlowed: %[AppID=String][ClusterID=String] [NodeID=String]: Timer thread has slowed beyond acceptable limits. Explanation Verification of the Unified CM internal timing mechanism has slowed beyond acceptable limits. This generally indicates an increased load on the system or an internal anomaly. Recommended Action If this alarm occurs at the same general day or time, or if it occurs with increasing frequency, collect all system performance data in Real-Time Monitoring Tool as well as all trace information for the 30 minutes prior to the time that this alarm occurred and contact the Cisco Technical Assistance Center (TAC) Error Message %UC_CALLMANAGER-6-DatabaseDefaultsRead: %[AppID=String][ClusterID=String] [NodeID=String]: Database default information was read successfully. Explanation Database default information was read successfully; this alarm will be removed in Unified CM release 10.0(0). Recommended Action Informational purposes only; no action is required Error Message %UC_CALLMANAGER-3-DeviceInitTimeout: %[DeviceName=String][Protocol=String][Side=UInt] [AppID=String][ClusterID=String][NodeID=String]: Device initialization timed out due to internal error. Explanation A device initialization timeout occurred because the device did not respond to an initialize request. If this alarm occurs in tandem with a configuration change, this may not indicate a problem unless this alarm recurs. Recommended Action If you are making a configuration change around the time that this alarm occurred, determine whether the problem still exists by calling the phone or placing a call through the trunk or gateway. If the call fails, reset the device. If the alarm recurs after resetting the device, review the System Reports provided in the Cisco Unified Reporting tool, specifically the Unified CM Database Status report, for any anomalous activity. You can also go to Real-Time Reporting Tool (RTMT) and check the Replication Status in the Database Summary page. If status shows 2, then replication is working. Check network connectivity to the server that is running the database. Error Message %UC_CALLMANAGER-3-NumDevRegExceeded: %[MaxDevices=Int][AppID=String][ClusterID=String] [NodeID=String]: The allowed number of registered devices has been exceeded. Explanation The allowed number of registered devices, as controlled by the Cisco CallManager service parameter Maximum Number of Registered Devices, has been exceeded Recommended Action If you did not expect to exceed the number of devices and you have auto- registration enabled, go to Device > Phones in Cisco Unified CM Administration and search for phones starting with "auto". If you see any unexpected devices which may not belong in the system (such as intruder devices) locate that device using it's IP address and remove it from the system. Or, if your licenses and system resources allow, increase the value in the Cisco CallManager service parameter, Maximum Number of Registered Devices. 5/24/26, 3:34 AM System Error Messages for Cisco Unified Communications Manager 15 - Cisco https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/err_msgs/15_x/ccmalarms15.html 259/343
