Thanks.
Here is when pidfile_open() creates the file:

and returns to cron. Cron is supposed to daemonize and then write to the
pidfile:
} else {
if (daemon(1, 0) == -1) {
pidfile_remove(pfh);
log_it("CRON",getpid(),"DEATH","can't become daemon");
exit(0);
}
}
pidfile_write(pfh);
but there's no evidence in the trace that it ever tries to write. Can
you also obtain a ktrace -i dump from cron?
