Question

由于我将PHP应用程序移动到新服务器（在32位Windows Server 2003 R2上作为Apache 2.2模块运行的PHP / 5.3.8），我在PHP错误日志中出现随机错误：

[09-Jan-2012 19:45:12] PHP Fatal error:  Out of memory (allocated 786432) (tried to allocate 17 bytes) in D:\site\util\odbc-connection.php on line 675
[10-Jan-2012 17:56:49] PHP Fatal error:  Out of memory (allocated 1310720) (tried to allocate 6144 bytes) in D:\site\logic\data.php on line 630
[10-Jan-2012 17:58:52] PHP Fatal error:  Out of memory (allocated 524288) (tried to allocate 393216 bytes) in D:\site\users\edit-user.php on line 458

我因以下原因感到困惑：

是达到memory_limit时收到的标准错误消息：

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 800001 bytes)

无论如何，memory_limit默认为服务器上的256MB，并且在此应用上设置为128MB（因此524,288字节应该不成问题）。
在报告的行中通常有相当无辜的代码，例如函数定义的开头......
```
function linea($html){
```
...或非常小的数组的foreach（）循环：
```
foreach($perfiles_basicos as $c => $v){
```

我想我已经放弃了所有明显的东西（我甚至在硬盘中的所有* .php，* .ini，.htaccess和* .conf文件中搜索了memory_limit字符串）我编写了代码来检测并记录对“128MB”限制的更改（没有找到任何内容），所以我现在很无能为力。

任何提示或想法？

更新＃1： Apache的error.log显示我从PHP获得内存不足错误后重新启动了Web服务器。有些是手动重启，有些是崩溃：

更新＃2： ...并且ODBC扩展程序正在记录以下错误：

No se puede cargar el controlador especificado debido al error del sistema  8 (Oracle in instantclient_11_2)

...其中system error 8映射到：

ERROR_NOT_ENOUGH_MEMORY 8 (0x8)没有足够的存储空间来处理此命令。

Answer 1

我刚刚在PHP树中快速搜索“Out of memory”，发现如果内部分配调用（例如malloc）失败，则Zend Memory Manager会触发此错误（{{3} }）。

所以，是的，听起来就像系统内存不足;）
