解决方法如下:

第一种可能：

去掉 php中 eaccelerator 的扩展
这样做能够解决您的问题，不过可能会加重系统负担
因为eaccelerator主要是为了节省系统资源的东西

具体做法是找到php.ini
如果是我帮您配置的，一般在c:/php/php.ini或者 c:/winnt/php.ini 或者c:/windows/php.ini

去掉

zend_extension_ts="C:\php\extensions\eaccelerator_win_xxx.dll"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="c:\temp"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

ea主要是在unix环境下开发的，但是作者忽略到windows实际上不像u主机那样，是没有u主机的那种内存共享机制的
这个bug已经提交给他们了，希望0.9.5能够解决

We have been using this PHP accelerator (0.9.5), on multiple servers, for a long time. It's used on some high traffic sites without any problem.
Install:
a) Download a copy of eAccelerator that is compatible with your version of PHP.
This can be an issue with eAccelerator. Sometimes it can take a little time before the Windows binaries are available for the most recent version of PHP.
b) Copy a compatible eaccelerator.dll to your PHP extensions folder (like:D:\php\ext replace with your actual folder location).
Make sure the configuration directive extension_dir in your php.ini is properly pointing to your extensions folder.
Like: extension_dir = "D:/php/ext"
//将dll文件复制到D:/php/ext下．
c) Create a folder (with the appropriate permissions) for the temporary cached files.
For example: D:\temp\eaccelerator
//创建tmp目录　权限可写
d) Add the following to your php.ini (as the first loaded extension):
.
;extension=php_yaz.dll
;extension=php_zip.dll
//编辑php.ini 在extension=php_zip.dll之后添以红字部分

[eaccelerator]
zend_extension_ts="D:\php\ext\eAccelerator0952_5.2.3.dll"
zend_extension="D:\php\ext\eAccelerator0952_5.2.3.dll"
eaccelerator.cache_dir = "D:\temp\eaccelerator"
eaccelerator.shm_size="64"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.debug ="0"
eaccelerator.check_mtime="1"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl ="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys= "shm"
eaccelerator.sessions="shm"
eaccelerator.c
zend_extension="D:\php\ext\eLoader0952_5.2.3.dll"
