Hi,

 

After upgrading from 6.0.4 to 6.2 I have problems with WAN connectivity falling out. I'm getting this message in de Fortios GUI:

 

Conserve mode activated due to high memory usage

 

I have tried to downgrade to 6.0.4 but can't with the error message that it failed beacause it cannot download the file from fortiguard. Help.

Hi,

 

Download the image from the Fortinet support website and upload/apply it from your browser.

 

Best regards,

Stephane

What was the resolution for this issue, if any ?

We have our firewalls on 6.0.8.

We have fixed a number of CPU/memory issues since then but we can only confirm the fix for the issues that were reported via Customer Support ticket, which has enough data point for the conclusion. So this really depends on your unique topology.

As a general reminder, please make sure to raise a Customer Support ticket for your own issue and provide as much debug information as possible. That's the only way we can review your issue and provide a proper fix. This forum is meant for quick report and it works well with simple issue but for complex issue, customer support ticket is the way to go.

Hi gcraenen, not sure if you were able to downgrade the image? Where did you try to download the firmware? Was it via FortiOS GUI or FortiGuard portal?

Hi,

we have the same Problem since one Year. We have 2 Fortigate 81E and Updated from 6.0.4 to 6.2.x and have these memory Problems, so we do a Downgrade to 6.0.x. There are no Problems.

Yesterday we tested the 6.4.0 and there are the same Problems again.
