Fortigate 60E high memory usage at boot with firmware 7.4.7

[bestpty]

Good day,

after upgrading our 60E to 7.4.7 firmware we noticed that just at boot the memory usage goes 60% used.

This has caused issues when it goes over 80% as all RDP session are dropped.

If we reboot the unit, it starts at 60% 

How can I check which memory process is eating that?

Perhaps I can apply this script for reducing memory usage:

Hi,

could you check your "General System Events" first and try to spot some strange behavior?
I ran into this issue at a 60F after 7.4.7 upgrade:

Here is a screenshot

Just try to doublecheck in the General System events if there are entry which indicates issues with IPS engine.
If I take a look on your screenshot, click "Logs" on the top left and then "General System Events" on the top right, there should be further information.

Otherwise try to check the last article I posted, thats also a problem, with IPS Engine.

Apparently, the IPS engine is killing me.
