I am having an issue getting all my pages to display in the site map. It only displays about 500 entries at a time. I have tried setting the index block to infinity and to a specific number. But no difference. Any suggestions?

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:template match="/system-index-block">
        <h1>Site Map</h1>
        <xsl:if test="count(system-page | system-folder[descendant::system-page]) &gt; 0">
            <ul>
                <xsl:apply-templates select="system-page | system-folder[descendant::system-page]"/>
            </ul>
        </xsl:if>
    </xsl:template>
    <xsl:template match="system-page">
        <li>
            <a>
                <xsl:attribute name="href">
                    <xsl:value-of select="link"/>
                </xsl:attribute>
                <xsl:choose>
                    <xsl:when test="title != ''">
                        <xsl:value-of select="title"/>
                    </xsl:when>
                    <xsl:when test="display-name != ''">
                        <xsl:value-of select="display-name"/>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:value-of select="name"/>
                    </xsl:otherwise>
                </xsl:choose>
