Strange occurrence in /var/log/messages

Apologies for the duplication , I forgot to include a
subject in the previous message.

At the bottom of /var/log/messages I see

Jul  1 07:35:01 home kernel: imklog 3.18.6, log source = /proc/kmsg started.
Jul  1 07:35:01 home rsyslogd: [origin software="rsyslogd"
swVersion="3.18.6" x-pid="2103" x-info="http://www.rsyslog.com";]
restart
Jul  1 07:35:01 home kernel: imklog 3.18.6, log source = /proc/kmsg started.
Jul  1 07:35:01 home rsyslogd: [origin software="rsyslogd"
swVersion="3.18.6" x-pid="2103" x-info="http://www.rsyslog.com";]
restart

(Some wraparound may have occurred in the above)

The same pair of messages is repeated. First time I notice such a
thing. In /var/log/kern.log I see at the bottom

Jul  1 07:35:01 home kernel: imklog 3.18.6, log source = /proc/kmsg started.
Jul  1 07:35:01 home kernel: imklog 3.18.6, log source = /proc/kmsg started.

Once again a duplication.

Is there any legitimate reason this might have happened or is it a
kernel bug ? Neither file has anything else I haven't seen before.
