FORTINET - Flash Disk full

Hi Experts,

I have an old FORTIGATE 200B.
Now I have seen the CPU was at 100% and I really don´t know why.
Also I have seen the FLASH DISK is 100% full.
Can this cause the problem ?

We had similar issue and its because of the FortiGuard signatures.
Flash disk usage shouldn't cause the problem. Have a look on which process is taking high cpu using command "diag sys top" and verify the settings according to the demon which is using more cpu.

Good Luck!

flash full could be caused by a corrupt filesystem. Do a "exec format-log-disk" on the command line to erase the contents (unless there are some logs you might still need). Please note that the system will reboot, so do not run during regular usage ...

Also do review log setting to purge or overwrite if necessary esp if it has been recurring..good to check against cpu usage for anomalous surge level and even explore for external log upload if legit events are high for this period
