Symfony2 bootstrap.php.cache 试图包含一个不存在的文件

Question

我们有一个 Symfony 2.6.8 应用程序，我们随机得到这个奇怪的错误日志：

[Thu Jun 11 12:29:14 2015] [error] [client 1.1.1.1] PHP Fatal error: require(): Failed opening required 'aab' (include_path='.:/usr/share/php:/usr/share/pear') in /data/apps/front/1.1.1/app/bootstrap.php.cache on line 2752

bootstrap.php.cache的第2752行是：

if ($file = $this->findFile($class)) {
    require $file; // line 2752
    return true;
}

findFile()方法是：

public function findFile($class)
{
    if (false === $file = apc_fetch($this->prefix.$class))
    {
        apc_store($this->prefix.$class, $file = $this->decorated->findFile($class));
    }
}

其他配置信息，我们正在使用：

Symfony 2.6.8
PHP 5.4.41
APC 3.1.13

我不明白请求的 aab 文件是什么。我们使用的是 APC 自动加载器，所以我怀疑 APC 的条目已损坏，因为重新启动 Apache2 时，应用程序正常运行。当应用程序处于这种状态时我无法调试，因为我们使用 apc.stat = 0 所以 php 文件不会在每次请求时重新加载。修改 bootstrap 无效。

可能是我们的APC设置不适应：

apc.cache_by_default => On => On
apc.canonicalize => On => On
apc.coredump_unmap => Off => Off
apc.enable_cli => Off => Off
apc.enabled => On => On
apc.file_md5 => Off => Off
apc.file_update_protection => 2 => 2
apc.filters => no value => no value

apc.include_once_override => Off => Off
apc.lazy_classes => Off => Off
apc.lazy_functions => Off => Off
apc.max_file_size => 1M => 1M
apc.mmap_file_mask => no value => no value
apc.num_files_hint => 1000 => 1000

apc.serializer => default => default
apc.shm_segments => 1 => 1
apc.shm_size => 128M => 128M
apc.shm_strings_buffer => 4M => 4M
apc.slam_defense => On => On
apc.stat => Off => Off
apc.stat_ctime => Off => Off
apc.ttl => 0 => 0
apc.use_request_time => On => On
apc.user_entries_hint => 4096 => 4096
apc.user_ttl => 0 => 0
apc.write_lock => On => On

欢迎任何提示！

正如这个问题中所解释的，这是完全相同的问题："Call to undefined method" after apache reload using apc opcode cache。

该错误来自 Apache2 为日志轮换重新加载。

删除 ApcAutoloder 解决了问题。
