Re: Several problems high memory and cpu usage blocking WAN connection after upgrade to 6.
We have 2 X 100D Hardware Appliances running firmware version 6.2.0-build0866 in NAT (Flow-based) Mode (HA: Active-Passive).
We too are seeing periodic spikes in CPU usage which occasionally puts the appliance in 'conserve mode'.
However, on running the 'diag sys top' command, I'm seeing a process called 'log_se' as the main culprit of resource usage, rather than 'ipsengine'. I also have an automated task configured to restart the IPS Engine out-of-hours.
I understand the 'log_se' process to be related to logging and the CPU usage spikes when I am viewing Web Filter, Application Control, Local Traffic logs etc. in the GUI. I can't run queries on these logs within the GUI for any length of time in fear of spiking the CPU and pushing the appliance into 'conserve mode'.
I'm wondering if both of these issues are related and it is not only the IPS Engine which is hogging system resources.
I will pose the question to Fortinet Support to get their view on it and will post any developments.
