High query getting Out of Memory

Hi, your site looks down at this time, this doesn’t seem to be a query issue(1.310 seconds is not a crushing cause time) what have you changed to your site before getting the issue? this looks like a bad php/wordpress script maybe a never end loop check also your ajax that is another place for error…
I don’t know what changes you’ve made but there is the place to start, if you don’t know of any changes… then you’ll have to disable all plugins, switch to default theme and enable them one by one until you get the faulty part…

<ul>

<?php require '../../../wp-load.php';  ?>
<?PHP require_once('../../../wp-blog-header.php');?>

<?php query_posts('showposts=4&cat=44'); ?>
 <?php while (have_posts()) : the_post(); ?>

	<li>
                            	<div class="image"><a href="<?php the_permalink() ?>"><img src="<?php $values = get_post_custom_values("thumbnail"); echo $values[0]; ?>" style="width:198px;height:115px" 

border="0" alt="" /></a></div>
                                <h3><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h3>

<p>   <?php $trim_length = 180;  //desired length of text to display
								$custom_field = 'description';
								$value = get_post_meta($post->ID, $custom_field, true);
								if ($value) {
								echo rtrim(substr($value,0,$trim_length)). '...';
								}
									?>
</p>

                                <div class="share">
                                    <h6><?php if(function_exists('the_views')) { the_views(); } ?></h6>
                                    <div style="float:left">
                                     <a href="https://twitter.com/share" class="twitter-share-button" data-url="<?php the_permalink() ?>" >Tweet</a>

twttr.widgets.load();
