[CentOS] needs-restarting: one server reports nothing te restart (after updating openssl) C6.5

Hi,

After updating openssl on most of my C6.5-servers needs-restarting reports at least sshd, ntpd and sendmail.
But on 1 server needs-restarting reports nothing. And yes, sshd, ntpd and sendmail are running.

All yum-utils are latest yum-utils-1.1.30-17.el6_5.noarch.

openssh-clients-5.3p1-94.el6.x86_64
ntp-4.2.6p5-1.el6.centos.x86_64
sendmail-8.14.4-8.el6.x86_64

At least ssh and ntp are straight out of distro and all my sendmails have the same configuration.

How reliable is needs-restarting?
Or how can this be explained?

Thanks
Patrick
