Hi,

Why puppet agent restarting everyday at 00:01 hours?

That's not the agent, it's the master. Logrotate cronjob (/etc/cron.daily)?

HTH...

I'm not entirely convinced that an agent with the listen option would
not start a WEBrick server as well.

But yes, logrotation and friends are a likely suspect.

Hi,

This is configured to run daily by puppet installation itself.   Does this restart puppet agent?

/var/log/puppet/*log {
  missingok
  notifempty
  create 0644 puppet puppet
  sharedscripts
  postrotate
  pkill -USR2 -u puppet -f 'puppet master' || true
  [ -e /etc/init.d/puppet ] && /etc/init.d/puppet reload > /dev/null 2>&1 || true
  endscript
}

Yes, it does, although it shouldn't. "/etc/init.d/puppet reload" sends a SIGHUP signal to the puppet agent, which restarts it. However, according to puppet-agent(8), this action should better be sending a SIGUSR2 ("Close file descriptors for log files and reopen them. Used with logrotate."), which wouldn't trigger an agent restart.

Should this be considered a bug in /etc/init.d/puppet?

Bye...

Becase of this restart.   My 1200 puppet agent runtime changed and so all 1200 puppet agents try to connect puppetmasters at same time because of this most of the agent in out-of-sync or error stat.

Suresh.
