pfsense gets unreachable suddenly

  • hi, I have pfsense which is installed on top of KVM, it has been running for 4 months.
    but sometimes it goes unreachable, for example, I cant see the LAN IP from my network. or pfsense cant access internet.
    once this happens I reboot my firewall and everything work again.
    I am running on version 2.4.2-RELEASE
    The link speed is 100baseTX <full-duplex>
    the hypervisor is ubuntu 16.04 with kernel 4.13.0-36-generic
    and I am not using virtio for my NIC's or DISK's
    can anyone help me?

  • No help, just confirmation that this occurs to more people.

    I am running pfSense in a virtual environment. When it works, it works. But randomly pfSense will block any incoming/outgoing traffic without clear warning. A reboot is the quickest method to resolve it.

    Apparent moment of the latest stop:
    Jul 19 06:00:00 [] /usr/sbin/cron[15210]: (root) CMD (/usr/local/bin/php /usr/local/www/pfblockerng/pfblockerng.php cron >> /var/log/pfblockerng/pfblockerng.log 2>&1)

    [IPs sensored.]

    Network traffic after this moment seems blocked, strangely logs are still going after this moment. Also web interface is reachable, host machine is fine.

    Anyone some clues how to get more things logged?
