+    &my-app; creates one thread (or process) for every incoming client
+    connection that isn't rejected based on the access control settings.
+   </para>
+   <para>
+    If the system is powerful enough, &my-app; can theoretically deal with
+    several hundred (or thousand) connections at the same time, but some
+    operating systems enforce resource limits by shutting down offending
+    processes and their default limits may be below the ones &my-app; would
+    require under heavy load.
+   </para>
+   <para>
+    Configuring &my-app; to enforce a connection limit below the thread
+    or process limit used by the operating system makes sure this doesn't
+    happen. Simply increasing the operating system's limit would work too,
+    but if &my-app; isn't the only application running on the system,
+    you may actually want to limit the resources used by &my-app;.
+   </para>
+   <para>
+    If &my-app; is only used by a single trusted user, limiting the
+    number of client connections is probably unnecessary. If there
+    are multiple possibly untrusted users you probably still want to
+    additionally use a packet filter to limit the maximal number of
+    incoming connections per client. Otherwise a malicious user could
+    intentionally create a high number of connections to prevent other
+    users from using &my-app;.
+   </para>
+   <para>
+    Obviously using this option only makes sense if you choose a limit
+    below the one enforced by the operating system.
