https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209233 --- Comment #10 from commit-hook@freebsd.org --- A commit references this bug: Author: kib Date: Thu May 5 10:20:23 UTC 2016 New revision: 299114 URL: https://svnweb.freebsd.org/changeset/base/299114 Log: Do not leak THR_FLAGS_SUSPENDED from the previous suspend/resume cycle. The flag currently is cleared by the resumed thread. If next suspend request comes before the thread was able to clean the flag, in which case suspender skip the thread. Instead, clear the THR_FLAGS_SUSPEND flag in resume_common(), we do not care how much code was executed in the resumed thread when the pthread_resume_*np(s) functions returned.
