Fortigate 80C stopped, need help.

Hi there, I an newbie here. Just got a problem for 80C. It stopped working occasionally, nobody could go to internet. When I login it show on Dashboard that Registration unreachable. AntiVirus, IPS and Vulnerability Scan all failed. CPU usage was around 95% high. When click on CLI Console it shows Connected but with error: Cannot read termcap database, using dumb terminal setting. All log file are missing. When I tried to reboot it just hang. I have to disconnect the power and wait for a few minutes. after trun it on normally it works fine. Checked the log after restarting, it stopped logging anything sometime a few hours ago. It seems this more often since this January. I am not good at Fortigate and CLI. If you have any ideas about this issue I am glad to hear. Thank you. The screenshot is below.

Hi Jerry. Welcome to the forums. I have noticed you have vdoms enabled -- was that your doing and/or do you actually need vdom support on the Fortigate? That may be your problem right there.

Hi Dave, We do have two VDOMs for two different networks. It worked well for the last eight months. You think that' s the problem?

No. I mean, you' ve got 2 obvious problems: high CPU usage and Fortiguard network not reachable. To check which process eats up your CPU cycles: - open the console - type ' diag sys top 10' - type ' P' - quit after a while, copy the text and post here FG network: - post your settings in System>Config>FortiGuard especially the closed section ' AntiVirus and IPS Options' - tell us how the FGT is connected to the internet (any intermediate routers? NAT?)

After a reboot try to run the following command on the cli: execute update-now (when running in vdom mode first type config global) if registration is still unreachable after a few minutes try to ping fortiguard: exec ping service.fortiguard.net

Thank you, Ede and Matt. I tried to connect to 80C https web interface this morning but cannot. It shows connection was reset. Internet seems work fine. I will try to restart it and then try those CLI command, when there are not too any users.

It works well now. But there are some problems somewhere. I cannot access all logs now. It just hang when I click any log like traffic log, event log. the high CPU usage and unreachable Fortiguard only happen when users cannot connect internet.

My guess is that you have a corrupt filesystem, Do a backup of config. Do a fresh format of the flash, and upload same firmware. Restore the config.
