Memory leaking

Everyone,

I have been experiencing this weird memory issue with firewalls running on the 6.5.4.5-53n code . Having a few TZ500 & a NSa 2650 running on that code. Memory keeps on increasing on a daily basis until 98-99% ultimately resulting in the firewall rebooting. The problem here is there are no users logged in or many things going on with the firewall that justifies high memory utilization. I remember upgrading them from 6.5.1.5-6n to get rid of the high CPU utilization problem.

Has anybody else been experiencing similar issues (see attached memory utilization trends) ? Need some help as I don't want the same thing to occur when I upgrade them to the latest code.

    Hi @amol_wani122,

    we're aware of some memory issues on the firmware version 6.5.4.5-53n and the latest firmware 6.5.4.6-79n has resolved quite a few so far.

    I would recommend you to upgrade both firewalls but before doing do, please review the release notes for any known issue that may cause issues into your environment.

    Best Regards,

    Hi @fmadia

    Thanks for responding. I did not find any known issues to be hindering the environment, so upgraded one of the firewalls to the latest code - 6.5.4.6-79n. The memory utilization so far on that one shows (started off at 60% after it booted) the same trend as earlier except that earlier there was a 1% rise for ~50 hrs & now it happens to be ~30 hrs. This is pretty strange & I do have a case open with the Support team for more than a week now & there has been no update as to what is causing this, let alone finding a solution to fix this issue.

    I believe the current workaround should be to keep rebooting the firewall every couple of weeks.

    Thoughts ?
