 VPS SOFTWARE:
 --------------------

 PHP 5.3.x
 MySQL 5.1.x
 Apache 2.2.x
 xCache 1.3.x
 Suhosin & SuPHP


 VPS SPECIFICATIONS:
 --------------------

 3.2GHz Dedicated CPU
 2GB Dedicated RAM
 CentOS 5.x


 xCache is given 48MB of RAM as Dedicated. PHP max. memory has been raised
 from 32MB to 64MB (we've tested it both ways).


 That said, we've commented out the standard Apache Configuration limits on
 CPU & RAM prior to submitting this ticket (we saw this in a previous
 ticket, so http.conf has already been modified).



 The issue here is that we're experiencing timeouts when trying to save any
 large amount of Text, PHP or CSS through the WordPress Admin Interface.

 If we exceed the size of the box (non-modifed, non-extended), it times out
 and the following error is logged:

 PHP Fatal error:  Out of memory (allocated 6291456) (tried to allocate
 491520 bytes) in /home/username/public_html/wp-includes/query.php on line
 1906



 Line 1906 is:

                 if ( !empty($q['category__not_in']) ) {
                         $cat_string = "'" . implode("', '",
 $q['category__not_in']) . "'";
                         $whichcat .= " AND $wpdb->posts.ID NOT IN ( SELECT
 tr.object_id FROM $wpdb->term_relationships AS tr INNER JOIN
 $wpdb->term_taxonomy AS tt ON tr.term_taxonomy_id = tt.term_taxonomy_id
 WHERE tt.taxonomy = 'category' AND tt.term_id IN ($cat_string) )";
                 }



 That doesn't really make the most sense to me, seeing as how it relates to
 categories, not the saving of a file.
