https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D210800 --- Comment #4 from commit-hook@freebsd.org --- A commit references this bug: Author: ed Date: Fri Jul 8 20:09:22 UTC 2016 New revision: 302448 URL: https://svnweb.freebsd.org/changeset/base/302448 Log: 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.
