Restart of syslogd every three hours ?

Hi,

I have a question about an OpenBSD 7.3 host that has syspatches up to
today (July 4, 2023).

I noticed in: /var/log/messages that the: syslogd process is restarting
every three hours:

/var/log/messages

Jun 18 11:00:01 server syslogd[83783]: restart
Jun 18 14:00:01 server syslogd[83783]: restart
. . .

I checked: man syslogd and looked at the cron tabs on the system and
there doesn't appear to be anything related to the restarts.

Is this normal and if so, what is the purpose of the restarts ?

Thanks,

-J
