+<h3>Summary</h3>
+
+ <p>This Multi-Processing Module (MPM) implements an exclusively
+ threaded web server that has been optimized for Novell
+ NetWare.</p>
+
+ <p>The main thread is responsible for launching child
+ worker threads which listen for connections and serve them when they
+ arrive. Apache always tries to maintain several <dfn>spare</dfn>
+ or idle worker threads, which stand ready to serve incoming
+ requests. In this way, clients do not need to wait for a new
+ child threads to be spawned before their requests can be
+ served.</p>
+
+ <p>The <code class="directive"><a href="../mod/mpm_common.html#startthreads">StartThreads</a></code>,
+ <code class="directive"><a href="../mod/mpm_common.html#minsparethreads">MinSpareThreads</a></code>,
+ <code class="directive"><a href="../mod/mpm_common.html#maxsparethreads">MaxSpareThreads</a></code>, and
+ <code class="directive"><a href="#maxthreads">MaxThreads</a></code>
+ regulate how the main thread creates worker threads to serve
+ requests. In general, Apache is very self-regulating, so most
+ sites do not need to adjust these directives from their default
+ values. Sites with limited memory may need to decrease <code class="directive"><a href="#maxthreads">MaxThreads</a></code> to keep the server from
+ thrashing (spawning and terminating idle threads). More information
+ about tuning process creation is provided in the <a href="../misc/perf-tuning.html">performance hints</a>
+ documentation.</p>
+
+ <p><code class="directive"><a href="../mod/mpm_common.html#maxrequestsperchild">MaxRequestsPerChild</a></code>
+ controls how frequently the server recycles processes by killing old
+ ones and launching new ones. On the NetWare OS it is highly
+ recommended that this directive remain set to 0. This allows worker
+ threads to continue servicing requests indefinitely.</p>

+ <p>This directive tells the server what stack size to use for

+ you will need to bump this number to a higher setting.</p>
