We’ve had an issue for the past couple of weeks logged with the Fortinet support desk for a FortiGate 40c locking up and requiring a restart daily. This router was running 4.0 MR3 Patch6. Even trying to schedule a daily restart didn’t help as the router locked up each day before 24 hours had passed.
Yesterday Fortinet released 4.0 MR3 Patch7. I applied this to the router after having to do a manual reboot yesterday and have so far found that the FortiGate has not required a restart this morning. I’ll keep an eye on it and update this post in the next week with any progress.
Edit: So far so good !
