FMC problem

Amen — Tue, 05 Jul 2022 07:12:27 GMT

We are using the physical Firepower with the FMC as a virtual server. Cisco Firepower 1140 Threat Defense (78) Version 7.1.0.1

We did a Firewall update in past and renewed the Certificate.

Seems like it worked well, and our AnyConnect Clients can connect and work as usual.

(Build 28)

The Only problem is the FMC, which seems to have a database issue.

We have no Logs of connections, no events, etc. … just as if the database is empty.

This is from a different version ( https://bst.cisco.com/bugsearch/bug/CSCvs80121 )

We first noticed the error at the 27^th of June, when the weekly config backup failed…

This error occurs multiple times a day

Overview when I want to see the unified Events for troubleshooting our VPN Clients, empty screen and an error message in the left bottom corner.

Is any known BUG matching this?

The only time I have seen similar behaviour for the FMCv is when the client has taken snapshots as backup for the FMCv. So, I don't suppose you are taking snapshots of the FMC?

The only way to get it up and running again was to re-install the FMC and restore from a backup.

You need to reinstall FMC and restore the backup

Hi,

I faced this before and as mentioned by @Marius Gunnerud, I had to rebuild
to fix. The fast rebuild is so the following:

- Build a 2nd FMC
- Creata HA pair with new FMC as secondary to sync the config (this
won't create issues with in the new FMC for logging)
- Switch roles
- Delete the old FMC

I did upgrade to 6.6.5.2 which solved the issue.
