FortiGate 80E memory conserve mode

Hello folks

 

We look after various models of FortiGate and don't have a problem. Except for the 80E which regularly enters memory conserve mode and drops sessions. Occasionally getting so bad we have to contact the site to get someone to reboot it, as remote management isn't even possible.

 

We've tried firmware version 6.0.5, 6.0.6 and are now on 6.2.1 but the symptoms are largely unchanged. It usually runs okay for a couple of days to a week and then the alerts come through. Testing is difficult as I'm trying not to impact the site too much.

 

Has anyone experienced anything similar and found a solution that works? So far not much luck with Fortinet support...

    Yes - exactly the same issue here.

     

    600D - Various versions of 6.2 and 6.2.1

     

    I don't recall the issue on 6.0.5

     

    No solution here, going to try support as well.

    conserve mode is sort of protection. Fortigates enter it when the run below 30% of free memory.

    Maybe you should look into your FGT to see what causes this memory usage?

    Actually - I jumped on with Support last Friday - they took a long look and the ipsmonitor and wad were consuming unusual memory amounts.  My tech confirmed issues for some with 6.2 and 6.2.1 - 6.2.2 expected soon to address those issues.

     

    He took a lot of logs and kicked it up to the next tier of support which I have not heard back from yet.

     

    Killing the wad and ipsmonitor process helps short term but the memory does keep climbing - hopefully this will be enough to prevent having to reboot every three days.
