Will work on reproducing the failures, and verifying the regression point. 1752058 3 ap 2021-04-19 17:10:08 -0700 It seems super unlikely to me that it's due to r275890. But must be very close to it. Perhaps r275889 or r275887? 1753356 4 jenner 2021-04-22 16:41:30 -0700 I've been trying for several days to reproduce the failures, and have been unsuccessful. I've ran on Debug, Release, and Production builds. I've iterated up to 10000 runs. And I've ran in parallel using child-process=1 and child-process=50. None of which have led to a reproduction of the failure. Due to this, I'm still uncertain of the regress point. 1759581 5 428469 thorton 2021-05-13 02:25:57 -0700 Created attachment 428469 Patch 1759585 6 428470 thorton 2021-05-13 02:32:30 -0700 Created attachment 428470 Patch 1759614 7 ews-feeder 2021-05-13 03:39:22 -0700 Committed r277429 (237677@main): <https://commits.webkit.org/237677@main> All reviewed patches have been landed.
