Hard to determine without bisecting as both revisions are very close. 1753476 1 cgarcia 2021-04-23 00:13:50 -0700 I can't repro, but I think it's a problem with the preconnect, not the soup update. Looks like an issue when a preconnect connection is stolen by a new request in libsoup. 1753542 2 cgarcia 2021-04-23 03:02:50 -0700 Managed to reproduce this with my system under heavy load and running the test with --repeat-each=10. It's indeed a libsoup bug, so this will be fixed once we upgrade to libsoup 2.99.5. See https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/212 1758181 3 cgarcia 2021-05-08 03:44:16 -0700 This is fixed now that we bumped the libsoup3 version.
