I have a 600C with a recurring crash problem. It is running 5.0.11, but the problem has persisted since 5.0.4 or so.
About every 1-3 months, the gui will show that all interfaces are connected at 1GBPS and that each port has sent/received approximately 191 billion packets if I over over a port (not shown below).
Once the gui reaches this state, it is usually about 2-3 days before the firewall stops working altogether.
At that point, I need to do a full power down/power off reset. If I just do a warm boot, it will not recover and will stop mid-boot with an error message.
Has anyone experienced anything similar with a 600C? I am beginning to think this is a hardware issue.
Suggestions welcome. Thanks.
Fortigate 600C 5.0.12, 111C 5.0.2
