Hi EtherMan , I really appreciate your prompt feedback as this is a very urgent issue . I have copied the system dump and pasted here . I can see the reason for failure is a process crash and the process is nodemgr . Would you know any reason why the process manager would cause a reboot. I am guessing the switch went to factory default judging from the output of "Show Switch".
And also, no I didn't load any config on the cli after the reboot. I still do not know what caused the reboot because the device has been running for years without issues like you said.
