https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217637 --- Comment #81 from commit-hook@freebsd.org --- A commit references this bug: Author: tuexen Date: Thu Apr 20 19:19:34 UTC 2017 New revision: 317208 URL: https://svnweb.freebsd.org/changeset/base/317208 Log: Syncoockies can be used in combination with the syncache. If the cache overflows, syncookies are used. This patch restricts the usage of syncookies in this case: accept syncookies only if there was an overflow of the syncache recently. This mitigates a problem reported in PR217637, where is syncookie was accepted without any recent drops. Thanks to glebius@ for suggesting an improvement.
