Fortinet Crash - 7.4.7

[huan588]

Recently upgraded my firewall fleet (about 15 60f's, 2 100f's)

We're experiencing a crash of some sort every 2-4 days.

Of course a ticket has been opened and they're working it, albeit very very slowly. Pretty disappointed in their lack of urgency and overall continued lack of code quality.

The crash debug logs from the console session has:

NP6XLITE: __np6xlite_tunmgr_write:61 timeout

Not sure if anyone has seen this or knows anything about this issue ---- we're experiencing a high impact when this crash occurs, of course.

a downgrade can be used as a workaround. Many administrators facing NP6 timeout issues on FortiOS 7.4.7 have reported that reverting to an earlier, more stable firmware version—such as FortiOS 7.4.6 (SD-WAN PROBLEM) better 7.4.5—helps avoid these crashes.

Important considerations before downgrading:

Backup Configurations: Always back up your current configuration before performing any downgrade.
Review Release Notes: Check the release notes for the earlier version to ensure no other critical issues might affect your environment.
Test in a Lab Environment: If possible, test the downgrade in a controlled environment first.
