https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D210800 --- Comment #5 from commit-hook@freebsd.org --- A commit references this bug: Author: ed Date: Tue Jul 12 06:25:28 UTC 2016 New revision: 302627 URL: https://svnweb.freebsd.org/changeset/base/302627 Log: MFC r302448: Don't forget to set sa->narg for CloudABI system calls. It turns out that this value is not used within the system call code under normal conditions, except when using tracing tools like ktrace. If we forget to set this value, it is set to random garbage. This may cause ktrace to hang indefinitely, making it impossible to kill.
