<ul></ul><p>I'm experiencing similar symptoms (pfSense hanging frequently), though with different hardware. My configuration hangs less frequently than yours (generally every 3-4 days, though it happened twice yesterday), but with identical symptoms: no WAN or LAN traffic, and no response to keyboard on the console. The entire system is unresponsive.</p>
<p>I'm running a Supermicro E300 setup with a Xeon D1518, but using only a single WAN/LAN setup. I have an HP unmanaged switch on the LAN side of the network, and have multiple (9) public IP aliases assigned to the WAN interface. Thinking the Supermicro might be the problem, I swapped the config to a RCC-VE 4860, which proceeded to also hang every couple of days. I've subsequently swapped back to the E300, which at least I can power cycle remotely.</p>
<p>Unfortunately, I don't see a lot of overlap with our services or packages - I don't have any of the packages you're using installed, and the only commonalities we have on services are dhcpd, dpinger, ntp, sshd, syslogd, and unbound (which I assume are fairly stable). I have both IPSec and OpenVPN running (about 100 clients connected in, full time), as well as FreeRADIUS 3. No other packages are installed.</p>
<p>I am running on a ZFS partition, 2.4.2_1. I also have igb interfaces. My configuration file was ported over from an APU2 originally installed as a 2.3.X NanoBSD install, if that matters. Originally I thought it might be something about going from a Nano->Full install, or possibly going from AMD->Intel hardware / NICs. The APU setup was reliable to a fault - the only time we ever had downtime was when installing an update. The new firewall was simply a full Backup / Restore from the old 2.3 setup. It has been unreliable from the moment we put it in (2 months now).</p>
<p>One other thing I have noticed though haven't been able to definitively confirm - I feel like the system may happen more frequently (more quickly) if I leave a connection to the pfSense WebGUI open.</p>
<p>All of that to say - I'm seeing something very similar in terms of behavior, but I have a very different hardware / pfSense configuration.</p>
<p>Are there any log files that persist after boot that we could look in to try to debug this problem?</p> pfSense - Bug #8335: System hang with LACP downlink to UniFi switch https://redmine.pfsense.org/issues/8335?journal_id=359852018-03-06T23:40:40ZMike Pastore

<p>Can you try a different switch?</p> pfSense - Bug #8335: System hang with LACP downlink to UniFi switch https://redmine.pfsense.org/issues/8335?journal_id=359862018-03-07T07:23:01ZJeff Wischkaemper

<p>Unfortunately not. 1) I don't have one, 2) it's a production server and 3) the installation is actually in a different state from where I am, making any swap like that quite challenging.</p> pfSense - Bug #8335: System hang with LACP downlink to UniFi switch https://redmine.pfsense.org/issues/8335?journal_id=361422018-03-29T14:26:12ZMike Pastore
<ul></ul><p>I can confirm that this is still an issue on pfSense 2.4.3-RELEASE and UnFi firmware <del>3.9.21.8191</del> 3.9.27.8537.</p> pfSense - Bug #8335: System hang with LACP downlink to UniFi switch https://redmine.pfsense.org/issues/8335?journal_id=362832018-04-08T07:32:09ZMike Pastore
<ul></ul><p>Some new information:</p>
<ul>
<li>It happens when LAGG Protocol is set to Failover. </li>
<li>It happens when one of the two network cables is unplugged. </li>
<li>It happens when the LAG group only has a single member interface.</li>
