/mcp[NormalPriorityQueueDepth=Long][LowPriorityQueueDepth=Long][AppID=String][ClusterID=String] [NodeID=String]: Unified CM has exited throttling caused by a previous signal congestion condition. Explanation Unified CM has exited the throttling state caused by signal congestion on a threaded process within Unified CM Recommended Action Notification purposes only; no action is required Error Message %UC_CALLMANAGER-2-MemoryThrottlingEntry: %[ConfiguredVMSize=Int] [ConfiguredFreeOrdBlocks=Int][ThrottledVMSize=Int][ThrottledFreeOrdBlocks=Int][AppID=String] [ClusterID=String][NodeID=String]: Unified CM has entered a memory throttling state; new call attempts are being rejected. Explanation Unified CM has initiated call throttling due to unacceptably high memory usage Recommended Action High traffic usage is generally the root cause of a memory throttling condition. Evaluate the load balancing amongst the servers in your deployment to determine if additional nodes are needed to handle the traffic. If the MemoryThrottlingExit alarm is not issued in a reasonable amount of time as deemed by your organization, or if the system is frequently triggering the MemoryThrottlingEntry alarm, contact the Cisco Technical Assistance Center (TAC) for assistance Error Message %UC_CALLMANAGER-5-MemoryThrottlingExit: %[ConfiguredVMSize=Int] [ConfiguredFreeOrdBlocks=Int][ThrottledVMSize=Int][ThrottledFreeOrdBlocks=Int] [MemoryThrottlingExitReason=String][AppID=String][ClusterID=String][NodeID=String]: Unified CM has exited a memory throttling state. Explanation Unified CM has ceased throttling calls and has exited the memory throttling state Recommended Action Notification purposes only; no action is required Error Message %UC_CALLMANAGER-3-DeviceCloseMaxEventsExceeded: %[TotalEventsReceived=UInt] [IPAddress=String][TCPHandle=String][MaxEventsAllowed=UInt] [NumberOfSkinnyDeviceThrottled=UInt][AppID=String][ClusterID=String][NodeID=String]: The TCP socket for the SCCP device has been closed due to excessive events in a 5-second period; under normal conditions, the device will reregister automatically. Explanation The indicated SCCP device exceeded the maximum number of events allowed per- SCCP device. Events can be phone calls, KeepAlive messages, or excessive SCCP or non-SCCP messages. The maximum number of allowed events is controlled by the Cisco CallManager service parameter, Max Events Allowed. When an individual device exceeds the number configured in that service parameter, Unified CM closes the TCP connection to the device; automatic reregistration generally follows. This action is an attempt to stop malicious attacks on Unified CM or to ward off excessive CPU usage. Recommended Action Check the CCM trace data for the indicated SCCP device to determine the reason for the high number of events. Confirm that the value configured in the Cisco CallManager service parameter, Max Events Allowed, is a suitable number for your deployment.
