commit-queue has been frequently failing to commit since we moved ews to github (see https://lists.webkit.org/pipermail/webkit-dev/2021-February/031686.html). Most of the times it succeeds on retry. One reason for that might be that there is a delay in syncing between svn.webkit.org and github.com (since we canonicalize the commits before pushing them to github which takes some time). Another reason for the failure is that sometimes between the time commit-queue updates to Tot, applies the patch and tries to commit; there might be another commit on trunk which modifies one of the file being modified in the patch (often ChangeLog), causing the file to be out of date. commit-queue should automatically retry to commit before giving up (while handling above situations appropriately).
