My crashes are caused by In FreeBSD, thr_kill() and thr_kill2() are non-
standard system calls used to send a signal to specific threads within a
process. They provide low-level thread signalling functionality and are
primarily utilized under the hood by FreeBSD's 1:1 Threading Library
(libthr) to implement standard POSIX pthread_kill() behavior.

Fix this it seems the system is doing it. Freebsd 16 I see many updates
today so I will see if there will be any more after the update.
