Explanation This may happen if disk is full or the file is in use. Recommended Action Using RTMT, check the disk utilization and correct any issue discovered. If you do not discover a disk space issue, try restarting the TFTP service from Cisco Unified Serviceability (Tools > Control Center - Feature Services). Stopping and restarting the TFTP service is useful because the Config File that the TFTP service is trying to save might be an existing file that is in use. If you still get this error, go to Cisco Unified Serviceability and enable Detailed level traces in the Trace Configuration window for the TFTP service and contact the Cisco Technical Assistance Center (TAC).

Error Message %UC_TFTP-4-ServingFileWarning: %[ErrorNumber=Int][FileName=String][IPAddress_Port=String] [Mode=String][OpCode=Int][Reason=String][AppID=String][ClusterID=String][NodeID=String]: There was an error during processing of file request.. Explanation This could happen if the requested file is not found by the server, or other error indicated by the "Reason" clause when processing the file request. Recommended Action You can safely ignore this alarm if the reason shown in this alarm is "File not found" and if that file is the MAC address-based file name for a phone that you are auto-registering; in that case, the phone is not yet registered with the database and so it is normal for the phone's file not be found. In the case that auto-registration is disabled, this alarm shows that the phone or device is not added to Cisco Unified Communications Manager (Unified CM). Either add the phone to Unified CM or remove the phone from the network. If you still get this error after removing the phone(s), go to Cisco Unified Serviceability and enable Detailed level traces in the Trace Configuration window for the TFTP service and contact the Cisco Technical Assistance Center (TAC). 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 62/343
