[mayaa-user:1024] mayaaのメモリリークにつきまして

[Hara Hara]

お世話になっております。　石川と申します。

Tomcat7+JDK6で稼働中のアプリで、スレッドダンプを取った時に下記のログが
出力されます。

"http-bio-8083-exec-5" daemon prio=10 tid=0x00007f035c0d4800 nid=0x6ecb runnable [0x00007f039cc1a000]

    at org.seasar.mayaa.impl.engine.RenderUtil.renderTemplateProcessor(RenderUtil.java:134)
の繰り返しが延々と続くのですが、「☆☆☆.mayaa#attribute」の部分は
<m:echo m:id="XXX">
    <m:if test="${aaa == 0 &amp;&amp; bbb == false &amp;&amp; ccc == true}">
            <m:doBody />
        </m:if>
</m:echo>
という処理のm:ifの部分で、「ID=XXX」にあたるものはHTML内に1か所しかありません。
スレッドダンプを取得した時はサーバーのCPUが100%になっていて、上記の状態のスレッドがいくつかありました。

何か改善策はありますでしょうか。
どうぞよろしくお願いいたします。
