As sendmail is also similarly affected, this is not an ntp issue. As the 
services start without monit, there may be a monit issue when run under 
FreeBSD 15+.

The issue with ntpd is that it forks a subprocess, with a pipe between both 
processes. The child process write "R\n" to the pipe. If the parent does 
not read two bytes it exits with an error. Just a guess here that monit 
might have its fingers in the pipe.

Also as this also affects sendmail under monit it's suggested a FreeBSD PR 
(bugzilla bug) be opened WRT monit. Let's have the monit maintainer look at 
it first.

It does (within /etc/rc.subr).

No, your assumption is incorrect. This smells of a monit issue.
