Hi,

I am using Fortigate 200D Firmware v5.4.1,build1064 (GA)

Recently, there is the message when I log in "Conserve mode activated due to high memory usage" Memory Usage 85%

Could you help me fix this issue?

Thank you.

    There could too many reasons for this happening to list here.  Fortinet KnowledgeBase website has quite a bit of info on this. First Google results: https://kb.fortinet.com/kb/documentLink.do?externalID=FD33103 , https://kb.fortinet.com/kb/documentLink.do?externalID=FD40012 

     

    But debug is time consuming and then you need to know to interpret the results. Have you considered updating firmware to more up-to-date one? 5.4.1 is very, very old, so even if you open the ticket with Fortinet TAC the 1st thing they will advise is to upgrade to the supported FortiOS version, at least 6.0.12.

    Thank you for your support.

    I try to upgrade firmware to 6.0.12 but can not download it from support.fortinet.com

    There is the message when I select download image firmware.

    "Sorry, you don't have any product covered by Fortinet support contract. Please contact Fortinet partners to purchase Fortinet support contract or Fortinet customer service team at cs@fortinet.com"

    Yes, you have to have a valid Support Contract assigned to your username in Fortinet website to be able to download firmware images. And if you try to keep the configuration, you have to upgrade in specific steps, so would need to download quite a lot of firmware images:
