Must be a bug.

And what do you see on CLI?

Hi @networkers 

 

I am Bill from Fortinet, and I would like to investigate your issue.
1. Could you please execute the following commands multiple times?

get sys status
diagnose sys top-mem 250
diagnose sys scanunit stats all
diagnose hardware sysinfo memory
diagnose autoupdate versions
diagnose debug crashlog read

2. What is your device version? Could you please share the backup configuration along with the output of step (1) to my official email: bhoang@fortinet.com?
I will review the logs and attempt to reproduce the issue in my lab to identify the root cause. Thank you

BIll
