Description:
------------
I use the Java feature to call a Lucene Proxy,
after a few hundert calls I get segmentation faults.

My php.ini:

java.class.path=/usr/share/php_java.jar:/usr/lib/j2sdk1.4.2_01/lib/tools.jar:/usr/lib/j2sdk1.4.2_01/lib/dt.jar:/u
sr/lib/j2sdk1.4.2_01/jre/lib/rt.jar:/opt/jakarta/lucene/lucene.jar:/opt/mysql-connector-java/mysql-connector-java
-3.0.8-stable-bin.jar:/opt/wddx/Java/wddx.jar
java.home = /usr/lib/j2sdk1.4.2_01 
java.library = /usr/lib/j2sdk1.4.2_01/jre/lib/i386/libjava.so 
java.library.path = /usr/share/extensions/no-debug-non-zts-20020429

Reproduce code:
---------------
$query = trim(urldecode($_REQUEST["keywords"]));

	$index = "/srv/www/lucene/index";

	$obj = new Java("org.ew.lucene.SearchEngine")
		or die("ARGHHHS");

	$result = $obj->search($index,"AND",$query)
		or die("ARGHHHS");


	$rs = wddx_deserialize($result);
	$meta = $rs["meta_data"];
	$rows = $rs["rows"];

	if (!stristr($rs,"No matches found for") && strlen(trim($rs)) >= 1)
	{
		....


Expected result:
----------------
A array with the Lucene results (works)

I get 50 segmentation faults on 10.000 searches

Actual result:
