From the middle of a script I've been able to isolate a (very sudden) issue with querying some data from MySQL using PHP. Using the same connection within the same API in the past, I have been able to do numerous (millions of) individual INSERT queries in the past. Also, I've been able to return and manipulate large SELECT result sets.
However, the following error has been occurring. The following returns 54265:
$status = mysql_query("SELECT * FROM Table_Name", $t_conn) or die("bad query");
echo mysql_num_rows($status);
And then, attempting the following stops at 23494:
$status = mysql_query("SELECT * FROM Table_Name", $t_conn) or die("bad query");
$i = 0;
while($dataset = mysql_fetch_assoc($status)) {
echo $i++."<br />\n";
}
The odd thing is that it matters whether or not I am saving the fetched data. The following stops at 6494:
$status = mysql_query("SELECT * FROM Table_Name", $t_conn) or die("bad query");
$i = 0;
$dataset = array();
while($dataset[] = mysql_fetch_assoc($status)) {
echo $i++."<br />\n";
}
This leads me to believe that I have an error with Apache or PHP. Looking at /var/log/system.log, the last line is:

Best, Mark
A hint from ircmaxell led me to execute the script from the command line. While error_reporting(E_ALL); was indeed on, the error wasn't displayed through apache. But, from the command line I received:
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 2048 bytes)
While 256M is already a pretty large amount of memory, at least I have a lead to go on and will try splitting up the task.
