Fortigate 200D crashing with 99% of memory in HTTPSD

[Daividdi]

Hi folks, today my appliance crashes three times with the same issue HTTPSD over than 99% memory amount.

Anybody can help me to solve this issue?

I'm getting similiar (though not 99%) httpsd as well. HV64 on Hyper-V

OS 5.4.3

I have a similar case with 900D and 5.4.4. In my case, the problem happens when doing FortiView > Destinations. After doing that, memory goes to 99% very rapidly, httpsd and dnsd go very high and the system enters conserve mode (but doesn't crash). The problem might be related to heavy traffic (in my case there is 24K sessions/sec and 1.4M sessions). Do you have a similar situation? I have opened a ticket one month ago and still there is no clue. If you open a ticket, you may mention my ticket number too: 2076783.
