Summary STP 96 stops loading pages after a while
Nigel Jones
Reported 2019-12-06 02:35:27 PST
Symptom Network connectivity stops completely I've now experienced this twice.. After using STP 96 for a while (a day or two since reboot this time), I experience a page not loading. nothing unusual there, until one goes to a different browser - for example google chrome, and find that the site/page is fine, and responsive. In my case I initially saw a failure to load a page from BBC iPlayer ie https://www.bbc.co.uk/iplayer . I then went to my 'gmail' tab to see it report 'not connected. connecting in 1s' . I type into the search bar, and get nothing (no dropdown showing search results, no google search). Going specifically to 'www.apple.com' and I just see the progress bar at perhaps 15% and not moving. I also tried my local router web page - same, and even http://127.0.0.1 I had been running a video (BBC newsnight) in PIP mode. It did stop a few times (oddly) and I had to go back to the main frame and do pip again - that was the only oddity. Using internal display & external 4K. MBP Pro 2016 Interestingly I don't seem to get an error, just an apparent hang CPU usage is normal (extremely low) I have in the order of 20 tabs open. Environment - Catalina beta 10.15.2 Beta (19C46a) - wifi (up to around 600 Mbps) - backend router 1 Gbps down / 50 Mbps (up) - no additional firewall/AV on mac I experienced page loading with issues prior to 96 as per https://bugs.webkit.org/show_bug.cgi?id=201822 Unsure what else I can capture. I clicked on 'report an issue' but of course bugreport.apple.com does not load If I open web inspector I see no activity - I get the usual tabs but the console has nothing in it, nor does timelines or network - even if I try and reload the page. I don't even get a page loading timeout, it just sits there It's as if the entire back end/network layer has given up. In /Logs/DiagnosticLogs I see nothign relating to safari - indeed nothing for the last few hours (as expected) Twitter, spotify, intellij, chrome, whatsapp, slack etc are all working just fine, so this doesn't seem a systemwide problem, ONLY safari tech preview. I also tried 'empty caches' - no change

I opened a new page in private mode - it hung too.

A search in console for 'safari' shows this pattern repeating - it may be the cache entries were after I hit clear cache (though it's 10 mins later now) but the network error unknown error code 1100 May be interesting? default 10:39:15.501580+0000 deleted com.apple.SafariTechnologyPreview.CacheDeleteExtension : 0 default 10:39:15.501924+0000 deleted com.apple.Safari.CacheDeleteExtension : 0 default 10:39:15.502542+0000 deleted PurgeableSpace result: { "CACHE_DELETE_ELAPSED_TIME" = "0.031671062";

If I can/remember I will leave up in broken state in case the team have any further debug info to request that would be useful, but it's unlikely I'll manage this beyond the day...

Comment 5 2019-12-06 12:17:47 PST
I left STP up all day (whilst using regular safari mostly) and can confirm it's still in the same state - no no error/timeout pages came up, the pages I left 'loading' still have a ~15% progress bar.

Thank you for the report! The most useful thing to do right after getting an error like this is to collect a sysdiagnose. You can press Cmd+Opt+Ctrl+Shift+Period or run "sudo sysdiagnose" in Terminal. Once you have it, please file a report with Apple via <https://feedbackassistant.apple.com>, attaching it there. Once you have the number for that report, please post it here to make it easier for us to find.

Comment 8 2019-12-08 03:36:35 PST
Thanks - I will do that if it reoccurs. Unfortunately just before that last post (sat eve in uk) I decided to restart STP (which worked fine) and shortly afterwards applied 19C56a. I'm using STP now but can't capture further info until/if it reoccurs. I'll bear those instructions in mind if it does so thanks.
