/mcpError Message %UC_SERVICEMANAGER-1-SystemResourceError: %[SystemCall=String][Service=String] [Reason=String][AppID=String][ClusterID=String][NodeID=String]: A System call failed.. Explanation System call failed. Recommended Action (1) Check the syslog for the system error number.(2) If the Alert is seen repeatedly, restart Service Manager (3) If the problem still persist, reboot the node. Error Message %UC_SERVICEMANAGER-3-ServiceManagerUnexpectedShutdown: %[ProcessID=ULong] [ServiceName=String][AppID=String][ClusterID=String][NodeID=String]: Service Manager restarted successfully after an unexpected termination.. Explanation Service Manager unexpectedly terminated. Service Manager has recovered but other components may be adversely affected. The only known causes of unexpected termination are adverse conditions such as hard power down, kernel panic, and readonly filesystem caused due to hardware or software. These conditions can corrupt the filesystem and database in ways that are unrecoverable. Repeat occurrences inevitably lead to corruption. It is critical to identify and remedy the cause of this unexpected termination. Recommended Action Always shutdown via CLI or platform UI. Do not yank the power-cord or press and hold the power button. Use the recovery disk to perform a filesystem check to identify and attempt to correct any errors that occurred. If errors are detected a rebuild and restore from backup is recommended. Use a redundant reliable power source such as UPS and leverage Uninterruptible Power Supply (UPS) Integration for Unified CM. Run hardware diagnostics to check for hardware failures. If unexpected terminations persist contact Cisco Technical Support for assistance. Error Message %UC_CWLCSS-5-SwitchesAndAccessPointReached75PercentCapacity: %[Reason=String] [AppID=String][ClusterID=String][NodeID=String]: The current record count for switches and access points has reached 75%. The maximum capacity is 50000. Explanation The current record count for switches and access points has reached 75%. The maximum capacity is 50000. Recommended Action Please review number of switches and access points and their activation status. Ensure the count is kept below this threshold to avoid service shutdown.
