    Hi,

     

    In your CLI just sort the processes by Memory usage to get a better view.

    diagnose sys top 5 25

    hit m once open to change the sort order to memory

    m also works in the diagnose sys top-summary screen.

     

    The IPS engine does use quite a bit of memory so don't be surprised by that to much.  What is this device configured to be doing in terms of throughput, UTM functionality enabled and such?

     

    Regards,

    Craig

    Soon you would have to when it enters into conserve mode. I would recommend you open a TT with TAC to get it looked. Likely a software bug, like one of our FG1500Ds, which encountered with 5.2.7. They recognized it as a software bug and we've been waiting for the new 5.2.8 release that supposed to have the bug fix. In our case "imd" process has been eating up memory gradually without any reason. But it doesn't happen to all the other FG1500Ds we have somehow.

    Uptime on the firewall seems to be 381 days according to your last attached picture...

    A reboot once in a while is a good thing. The next thing to try is newer code. If you open a case with the support, the first suggestion they will give you is to upgrade anyway. My suggestion is to go up one step at a time, and check how that works. Be careful to always back up your config before upgrading, since downgrading config isn't supported.
