Fortinet Crash - 7.4.7

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.
