Hello Francois, <br>
<br>
Thank you for the comprehensive walk-through. It seems that you
are correct. The server restarts at a period of every 5 minutes
that might be triggered by the agent. I checked my firewall and
all policies that might affect the communication of the check
script and everything is working now. It's just now that I know
that the agent has a check for the server processes itself. Thank
you very much! Everything is working perfect!<br>
<br>
Thanks, <br>

OK, super !<br>
<br>
For posterity, I added the solution on serverfault:

Hello, <br>
<br>
<br>
OK, so it seems that your server is restarted after ~5
minutes. That really looks like an action of the agent on the
server. <br>
<br>
Before anything else, could you please give us:<br>
<ul>
<li>OS of the server on which Rudder is installed (type
(Linux, etc), distribution, version...)<br>
</li>
<li>Version of Rudder<br>
</li>
</ul>
<br>
Now, for the possible explanation: we have a configuration
rule on the server that's saying "the rudder server must be up
and accessible. If not, try to restart it". <br>
The rule is checked by accessing URL <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://localhost:8080/rudder/api/status">http://localhost:8080/rudder/api/status</a>
and expecting a "OK" text response with 200 OK status. <br>
<br>
So, could you please try:<br>
<br>
<ul>
<li> to execute the following command as rood on the Rudder
server: </li>
</ul>
<blockquote>
<blockquote><tt>$ </tt><tt>/var/rudder/cfengine-community/bin/cf-agent
-KI</tt><br>

And ckeck if there is something like that in the output:<br>

If so, after Rudder restarted, execute the following command
by hand: <br>
<br>
<blockquote><tt>curl -v -X GET <a moz-do-not-send="true"

</tt></blockquote>
<br>
If that fails to return "HTTP/1.1 200 OK" and "OK", there is
something forbidding the test to succeed. Did you change the
"rudder.rest.allowNonAuthenticatedUser" value in config file
/opt/rudder/etc/rudder-web.properties ? Do you have some
firewall filtering connection from localhost to itself ? Or
perhaps it is something about IPv6 localhost not resolving
correctly. <br>
<br>
For that last case: Java try very hard to use IPv6 over IPv4,
so if you have in /etc/hosts:<br>
<blockquote>::1 localhost<br>
</blockquote>
It will leads to problem. <br>
<br>
Try changing that to:<br>
<blockquote>::1 ip6-localhost<br>
</blockquote>
And check that you have a line looking like:<br>
<blockquote>127.0.0.1 localhost<br>
</blockquote>
<br>
<br>
Hope it helps, <br>
<br>

Hello Francois, <br>
<br>
Thank you for your response. Once in a while, I encounter an
error message "Cannot contact the server at this time." which
refreshes the page I'm on and shows an animation "Rudder is
loading, please wait". After then, I end up on the login page.
Upon investigation of the log files, I found that the
application might be triggering a "graceful" shutdown. I've
enclosed the relevant log file for your closer inspection.<br>
<br>
Thanks, <br>
Bert<br>

<pre wrap="">Hello,
I'm encountering periodic restarts of the rudder root service. This results of me being dropped from my current web session and prompts me to log in again. Is this an intentional behaviour or did I misconfigure something?
Thanks,

<br>
<br>
Hello, <br>
<br>
Periodic restart are not an intentional behavior, so there
seems to have something not cool is happening. <br>
<br>
First, perhaps the application is not really restarting. Do
you see any wainting screen ("Rudder is loading, plea wait")
befor being redirected to the login screen ? <br>
Does the PID of the application is changing during these
events ? <br>
You can know the PID of Rudder server with command: <br>
<br>
$ ps aux | grep rudder | grep java<br>
<br>
If Rudder is not restarting, perhaps the problem is on the
authentication part (for example, at some point, the server
is loosing your authentication cookie and so ask you a new
authentication). <br>
<br>
If the application is restarting, could you please tell us
if there is any errors in the log:
/var/log/rudder/webapp/xxxx_stderrout.log ?<br>
<br>
Thanks, <br>
