定期冻结 - 可能与CoreAnimation有关？

几个月来，我经常在运行OSX 10.9.2的Macbook Pro 8,2上遇到锁定。实际上，我在10.8中得到的是一个相关的问题。我有2.3GHz Core i7处理器，8GB内存和三星840 Pro SSD。我已经开始认真地尝试调试这个问题，这可能每周发生一次或两次（我是一个沉重的用户，所以这是相对不常见的），因为我的AppleCare在几个月内结束。

冻结是突然的，我没有注意到他们已经发生，直到我尝试使用触控板。所有图形保持不变，但没有其他工作。我不能用Cmd + Tab。任何播放的视频或音频都会停止播放。要重新启动，我必须按住电源按钮。

我尝试过常用的维护工作：

• 我用ONYX彻底清理和重建了。
• 我已将Firefox，Dropbox和Jottacloud更新到最新版本。
• 我一直在所有OSX更新之上。
• 我进行了完整的内存测试。
• 我没有遇到问题就运行了CINEBENCH基准测试。

我现在正在寻找日志寻求帮助。这是我冻结后今天发现的：

我假设netbiosd警告与我阻止Little Snitch的流量有关。我怀疑这会导致冻结（虽然让我知道我是不是错了）。我目前对CoreAnimation警告持怀疑态度。我在之前的崩溃之前已经注意到了这些，尽管有时它们似乎在日志中，即使没有发生崩溃。这有可能导致我的问题吗？如果是这样，什么是CoreAnimation，我该如何解决？

请注意，我在这个系统中使用的是我的第三个SSD，并且（虽然我有保修更换）我一直怀疑这个系统的某些东西正在煎炸他们，因为他们都在冻结后就死了。现在我忽略了这种怀疑，并试图系统地跟踪日志，但如果您认为这些SSD问题可能表明某些事情，请告诉我。

更新：我刚刚发生了另一次崩溃，并在我的控制台中找到了以下信息。我想知道这个“先前停机原因”部分告诉我们的是什么。
