Netgate 2100 Stalling - HW issue?
-
Yup, the other monitoring graphs may show something there; a spike in CPU usage or states perhaps. Or a gap in data would also be telling.
This doesn't look like a hardware issue to me. Or at least if it is it's unlike any hardware issue I've seen before!
Are you running from eMMC or SSD?
-
See attached. To be honest I'm not seeing any hints here. I took some time to really try to quantify exactly how long the stalls are. I think my 4 minute upward bound estimate previously was just bad luck. Watching carefully over about a half hour, the longest stall was 97s, shortest was 4s, average was about 31s.
Since the minimum resolution of these graphs is 1m, I think it ends up smoothing over these stall durations.
It's running on the eMMC that came with the device.
-
Other metric in the monitoring graphs may show something.
The fact the traffic graphs appear to stop updating rather than go to zero implies something significant is happening. Either the RRD-update process stops or it's unable to get the data. Since it looks like other graphs continue it seems more like it can't get data. I'm surprised there is nothing in the system log at that time. It really feels like pf stops responding.
-
So just to be clear, here's the entirety of the logs in System Logs / System / General for this afternoon while this behavior was ongoing. Logs are the same earlier in the morning when I was doing the screenshots of the performance metrics. Just a bunch of the sshguard spam which seems like a known benign issue (https://forum.netgate.com/topic/169923/tons-sshguard-log-entries-and-its-not-enabled/14).
But also, the frequency of the sshguard log entries is much less than the drop-outs, which happen every 1-2 minutes while the sshguard entries are approximately every 24 minutes.
I agree with the instinct that this is pf hanging because active connections are never affected during the outage, but zero new connections can be established during the outage time regardless of device. I've also confirmed that during the outage, the WebUI of pfSense itself is also stuck. No clicks to other screens etc work until the outage clears. But I'm at a loss for how to investigate further since the logs are so silent on this topic.
-
Yes that sshguard restart is usually just log spam and not important. However we have seen issues where the log compression can put significant loading on the firewall. The fact sshguard is restarting implies the logs are rotating every ~20mins. You should check which log is filling and rotating. And I would disable log compression at least as a test. That's in Status > System Logs > Settings.

Check the eMMC status, just to be sure it is OK and not the root cause. -
It looks like the default checks to log blocked traffic were putting a lot of logs in the Firewall logs so I turned those off. Confirmed that compression was in the default "none" configuration.
What I'm really struggling with on all of this is we're now dealing with a factory-default device. I reflashed it and did not restore my backup and the behavior is unchanged. This feels like a glaring red flag to me.
Also checked the eMMC and looks like it's healthy with 0-10% of life consumed and Pre-EOL of Normal. Full report below.

Hmm, I've never seen a hardware issue present like that though. If it's not a config problem it could be an environmental issue, something in the local network causing a connectivity problem. Somehow.
-
@stephenw10 the prior device that RMA'd with this behavior was ticket INC-96963. Any chance that device was investigated when it came back?
-
@sammiorelli
Is it possible that you have enabled flow control on the network, for example, on the switch?
Did you try to continuously ping pfSense from the PC and vice versa? -
Hmm, that must have been a while ago, we no longer use that ticket system. Do you have the serial number or NDI from it? You can send it to me in chat.
Was that 2100 installed in the same location? Same network?
