Things were<br> working fine (latency remained acceptable - YAY SQM!) My upstream pipe<br> (slow as it is) was totally filled by the three competing uploads, and<br> Netflix was doing its best to show me the West Wing.<br><br> A couple times during the evening, the Netflix stream just crapped out<br> and I lost the connection. (Infinite buffering message on-screen,<br> couldn't get to Google, etc. The LuCI GUI showed uptime of a minute or<br> so, and then things were fine again.)<br><br> I now have OpenWrt 19.07.1 installed, and have a little bandwidth for<br> repeating the experiment.<br><br> What debugging information should I turn on/look for in case this<br> happens again? Thanks.<br></blockquote><br>If the box reboots, this sounds like a kernel oops. In which case, we'd<br>really need a kernel stack dump to debug it. Which I'm not sure there's<br>a good way to get on OpenWrt without attaching a serial console :(<br><br>Unless of course you can find a reliable way to reproduce it without too<br>much delay, in which case someone with a serial console can take a look,<br>I guess :)<br><br>-Toke<hr>Bloat mailing list<br>Bloat@lists.bufferbloat.net<br><a href="https://lists.bufferbloat.net/listinfo/bloat">https://lists.bufferbloat.net/listinfo/bloat</a><br></pre></blockquote></div><br>-- <br>Sent from my Android device with K-9 Mail.
