I had one of our 3 node^s in a ring topo undergo automatic system resets.
According the troubleshooting guide an Automatic system reset occurs when you do an IP change or perform any other action that causes an automatic card-level reboot. The issue is that the node was not worked on at that time nor did any one else. What is strange is that the first error entry is an SNTP host failure and 3 seconds later the two TCS cards in slot 1-1 and slot 1-8 undergo an AUTORESET. I have read trough the troubleshooting guide version 9.4 but can not correlate the errors with this behaviour. I am unable to read the diagnistics file because this can only be read by Cisco. Underneath you will find all logging for last Sunday.
