Something is causing our database to go crazy. Is having these three queries in a row a possible problem?
<ul>
<?php
query_posts(array('category__in'=>38082, 'order-by'=>'post_date','order'=>'DESC','posts_per_page'=>'5'));
while (have_posts()) : the_post();
?>
<li><a href="<?php the_permalink(); ?>"><?php echo the_title()?></a></li>
<?php endwhile; ?>
<?php wp_reset_query();?>
</ul>
<ul>
<?php
query_posts(array('category__in'=>1, 'order-by'=>'post_date','order'=>'DESC','posts_per_page'=>'5'));
while (have_posts()) : the_post();
?>
<li><a href="<?php the_permalink(); ?>"><?php echo the_title()?></a></li>
<?php endwhile; ?>
<?php wp_reset_query();?>
</ul>
