ffdb config-error-log appear after fortigate 201F and 101F upgrade from v7.0.12 to v7.2.5

Hello Everyone,


Wanna check if it is only a DB not up-to-date issue and is it a common known issue since the same issue found in all of my FortiGates upgrade scenario. 


-Upgrade from v7.0.12 to v7.2.5

-201F standalone

-201F HA A-P cluster

-101F HA A-P cluster

-All of the forigates were using 1 month trial license and still vaild.

-FortiAnalyzer was configured but not connected before and after upgrade.

-Only mgmt port connected and have access to Internet behind simple source NAT from next hop gateway (a cisco router).


After around 2 hours wait, all the "xx signature is missing" messages were gone.


Messages of config-error-log found right after upgrade first boot

Hi FortC,


I may not be able to help much, but the

diagnose debug config-error-log read

gives out that after a boot there were parts of the config that could not be read and would be dropped.

execute update-now

I expect this to resolve that issue as it updates the ISDB as well.

As of such - the reboot was done because of an upgrade (which often means some sort of migration) or some maintenance only?


Best regards,





You are matching the known issues 774460.



config-error-log debugs shows Internet Service Database related errors when upgrading from 7.0 to 7.2, which causes confusion when the Internet Service Database was updated successfully.


This is not an issue, it is an expected behavior when OS upgrade happens from 7.0 to 7.2 due to the db differences. The errors/logs will start as soon as the device boots up with new OS (7.2), but the system will perform an automatic update-now soon and the errors will be gone after that.

There is no solution/fix required for this and you can safely ignore these.

- Have you found a solution? Then give your helper a "Kudos" and mark the solution.
