hi all

we are using 1000D fortigate and observing high memory usage(86%) but CPU&Disk usage is normal(3% & 9%).

IPS,Application & web-filter are enable on that.

can anyone explain what is exact reason behind this miss behavior & how to resolve?

Thanks in advance.

Hi,

Did this happen over time, or suddenly?

My experience with our Fortigate 500D is that memory is building up over time and a reboot brings it back to normal values. But a few weeks ago I upgraded to 5.4.5 and the memory looks to be stable now.

My advise: reboot the firewall and monitor the memory over time.

BTW, when the memory goes above 80%, the firewall goes into converse mode and will switch off some features.
