Question

我的IIS非常不稳定，因为它总是因为某种原因重新启动它与APC相关。

服务器的规格低于

Intel R Xeon  CPU 3GHZ 3GHZ
2GB RAM
64bit

APC＆amp;服务器规范

3.1.7-dev 
PHP Version 5.3.6 
APC Host localhost 
Server Software Microsoft-IIS/7.5 
Shared Memory 1 Segment(s) with 1024.0 MBytes 
(IPC shared memory, File Locks locking)  



extension=php_apc.dll
apc.shm_size=1024M
apc.num_files_hint=10000
apc.user_entries_hint=10000
apc.max_file_size=5M

错误的PHP日志文件

我无法弄清楚导致IIS重启的错误是什么导致 apc_fcntl_lock失败的错误：6 。我的项目存储了高达1GB的缓存数据，因此解释了shm设置为1024M

当我在浏览器上重新加载apc.php页面时，似乎更常出现问题 HTTP错误500.0 - 内部服务器错误 C：\ PHP \ php-cgi.exe - FastCGI进程意外退出

我的缓存被重置，我将再次重新缓存我的数据。

我的LINUX服务器工作正常。我的APC配置有问题吗？

Answer 1

我认为这不是APC配置本身的问题，但更可能是在Windows上处理文件锁定的问题。我在APC源代码中查找了apc_fcntl_lock，它非常简单，并且几个月没有更改。

如果您只运行一个工作进程，则可以尝试设置apc.write_lock = 0并查看是否有帮助。

否则，您可以尝试使用旧版本的PHP（或5.3.7RC3），以防APC与PHP交互的方式出现问题（尽管可能不太可能）。

最后，如果这不起作用，可以尝试不同的操作码缓存;例如xcache。

Windows上的APC iis 7.0不稳定
