====== Opsview ======
Opsview is a nice wrapper for Nagios, but the opsview_web_server.pl perl interface sometimes forks out of control.  Limit the number of processes that can start.

<pre>
if [ &quot;$USE_LIGHTTPD&quot; = &quot;0&quot; ] &amp;&amp; [ &quot;$USE_PREFORK&quot; = &quot;0&quot; ]; then
    ulimit -u 11
    script/opsview_web_server.pl -f -b --pidfile $pidfile
    RETVAL=$?
