Here's an example: http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/9903 http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/9904 http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/9905 The test only failed in build 9904. The test output said: ALERT: Test 69 failed: timeout -- could be a networking issue I don't think this is a new issue, but only recently have the bots been green enough to notice it. 360798 1 aroben 2011-03-02 08:01:40 -0800 Here's test 69: http://trac.webkit.org/browser/trunk/LayoutTests/http/tests/misc/acid3.html?rev=60999#L2437 360801 2 aroben 2011-03-02 08:04:39 -0800 Apparently for a test to time out, it must return "retry" 500 times in a row. Test 69 returns "retry" in this case: if (kungFuDeathGrip.title.length < 7) return "retry"; Looks like kungFuDeathGrip.title gets set up in test 65 by loading a bunch of iframes: http://trac.webkit.org/browser/trunk/LayoutTests/http/tests/misc/acid3.html?rev=60999#L2306 So I guess we're stalling while waiting for those iframes to load? 360809 3 aroben 2011-03-02 08:33:52 -0800 <rdar://problem/9075086> 367716 4 aroben 2011-03-15 09:47:59 -0700 This just happened again: http://build.webkit.org/builders/Windows%207%20Release%20%28Tests%29/builds/10417 369083 5 aroben 2011-03-17 09:33:45 -0700 And again: http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r81355%20(10512)/results.html 369176 6 aroben 2011-03-17 11:20:56 -0700 And again: http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r81363%20(10517)/http/tests/misc/acid3-pretty-diff.html 377773 7 aroben 2011-04-01 07:01:24 -0700 This is one of the most-frequent causes of flakiness on the Windows 7 bots.
