openssh-server reports error during shutdown

I get a red asterisk in shutdown log for openssh-server. I attribute it to line 87 in https://git.alpinelinux.org/cgit/aports/tree/main/openssh/sshd.initd\#n87:

if [ "$RC_RUNLEVEL" = "shutdown" ]; then
        _sshd_pids=$(pgrep "${command##*/}")
        if [ -n "$_sshd_pids" ]; then
            ebegin "Shutting down ssh connections"
            kill -TERM $_sshd_pids >/dev/null 2>&1
            eend 0
        fi
    fi

To be more precise I think that red asterisk is related to

kill -TERM $_sshd_pids >/dev/null 2>&1
