  Hey Markus,

  The first thing that jumped out at me from above was how you call your
  bundle to copy the file:

  ,----
  | methods:
  |   "any" usebundle => filecollector("$(cf_clients)"),
  |      action => silent_sometimes;
  `----
  You reference the list of clients with `$'. So, the bundle will be
  actuated once for each client. Have you instead tried passing the list
  so that the bundle is called just once and the iteration on the client
  happens inside the bundle?

  Like:

  ,----
  | methods:
  |   "any" usebundle => filecollector("@(cf_clients)"),
  |      action => silent_sometimes;
  `----

  Regarding the maximum number of connections, I see that you mention
  setting `control_server_maxconnections', note that variable is used by
  body server control (cf-serverd). For your policy, where you have one
  agent that is creating a bunch of connections from cf-agent you might
  consider setting `default:def.control_agent_maxconnections'. It's set
  to 30 in the MPF by default.

  I would link you to the docs that mention it, but it doesn't seem to
  be explicitly called out yet so I just filed an issue about it here

Hey Markus,
</p>

<p>
The first thing that jumped out at me from above was how you call your bund=
le to copy the file:
</p>

<div class=3D"org-src-container">
<pre class=3D"src src-cfengine3"><span style=3D"color: #a89984; font-weight=
: bold;">methods</span>:
  <span style=3D"color: #689d6a;">"any"</span> usebundle =3D&gt; filecollec=
tor<span style=3D"color: #689d6a;">(</span><span style=3D"color: #689d6a;">=
"$(cf_clients)"</span><span style=3D"color: #689d6a;">)</span>,
     action =3D&gt; silent_sometimes;
</pre>
</div>
<p>
You reference the list of clients with <code>$</code>. So, the bundle will =
be actuated once for each client. Have you instead tried passing the list s=
o that the bundle is called just once and the iteration on the client happe=
ns inside the bundle?
</p>

<p>
Like:
</p>

<div class=3D"org-src-container">
<pre class=3D"src src-cfengine3"><span style=3D"color: #a89984; font-weight=
: bold;">methods</span>:
  <span style=3D"color: #689d6a;">"any"</span> usebundle =3D&gt; filecollec=
tor<span style=3D"color: #689d6a;">(</span><span style=3D"color: #689d6a;">=
"@(cf_clients)"</span><span style=3D"color: #689d6a;">)</span>,
     action =3D&gt; silent_sometimes;
</pre>
</div>

<p>
Regarding the maximum number of connections, I see that you mention setting=
 <code>control_server_maxconnections</code>, note that variable is used by =
body server control (cf-serverd). For your policy, where you have one agent=
