从脚本的中间,我已经能够隔离一个(非常突然的)问题,即使用 PHP 从 MySQL 查询一些数据。过去在同一个 API 中使用同一个连接,我过去能够执行无数(数百万)个单独的 INSERT 查询。此外,我已经能够返回和操作大型 SELECT 结果集。

但是,出现了以下错误。以下返回 54265:

$status = mysql_query("SELECT * FROM Table_Name", $t_conn) or die("bad query");
echo mysql_num_rows($status);

然后,尝试在 23494 停止以下操作:

$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";
}

奇怪的是,我是否保存获取的数据很重要。以下停在 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";
}

这让我相信我在使用 Apache 或 PHP 时遇到了错误。查看/var/log/system.log,最后一行是:

来自 ircmaxell 的提示引导我从命令行执行脚本。虽然错误报告(E_ALL);确实打开了,错误没有通过apache显示。但是,从命令行我收到:

PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 2048 bytes)

虽然 256M 已经是一个相当大的内存量,但至少我有一个线索可以继续,并且会尝试拆分任务。
