Yes and yes.

After updating, I got this crash report error right after logging into the GUI:

Crash report begins.  Anonymous machine information:

No FreeBSD crash data found.

Is that pretty much expected with snapshots?

If it was during the update it could well have been since the library version may have been updated resulting in the wrong lib being present at some point.
As long as it doesn't return if you remove it a reboot you're fine.

Yeah, it didn't show anymore after a reboot so I'm good. Although the upgrade to dev didn't really fix the latency issue, it seems to be better now and I'm still convinced that it's an ISP issue. I'm having a 24ms RTT to 8.8.8.8 now which is ideal but RTTsd is still erratic. What does a high RTTsd mean?

stephenw10

It means there's a large variation in ping round-trip times. Standard Deviation.

Steve

@stephenw10 Right, that I get. But does this usually to translate to an unstable Internet experience?

stephenw10

Probably not, it depends how high you are seeing. But, for exmaple, if all your pings are exactly 10.0ms and then you see one at 10.9 that's going to be a high deviation. You would not notice a 0.9ms change though.

Ok, then this is super insane, wouldn't you say?

stephenw10

It's certainly much larger than I would expect. Rttsd values are usually and order or mangnitune less than the actuall RTT time. Like:

Are you actually seeing ping spikes to 8.8.4.4?

Steve

kevindd992002

Right now, I do. But that's probably because there was a recent submarine cable cut in SEA that our ISP is using. The latency problem, however, started happening way before that submarine cable cut issue. I tried using the mtr package and I see the same spikes after 100 pings to each hop.

stephenw10

Might just be how your link behaves then.
