首先，我向你道歉，如果这对你来说，显然是硬件问题，而不是编程问题。如果是，希望我们可以将其迁移到适当的位置。
我有一个长期运行的Web服务程序（任何CPU），它有一大堆数据存储库保存在内存中。有些是每小时刷新一次，有些则不经常刷新。其中一些存储库在从第三方源检索数据后对数据（简单POCO）进行排序。
在蓝色的月亮中，我在AccessViolationException期间在方法ComputeKeys内得到Sort。其中一些存储库在从第三方来源获取数据后使用List<T>.Sort。
执行这些排序的代码很简单，取决于存储库，但这里有两个例子：
pocos.Sort((a, b) => a.BookingDate.CompareTo(b.BookingDate));
或：
pocos.Sort((a, b) => a.Date.CompareTo(b.Date));
请注意，这些数据集相当大（相对而言）。一个有超过140,000个元素。我将异常记录到数据库中，这是我的日志（时间与我所拥有的另一个日志相关，表明存储库当时正在完成获取数据）：

正如你所看到的，它几乎同时发生在两个人身上。因此，我想知道这不是一个.NET /编程问题 - 而是一个硬件问题。请注意，它们都是虚拟机，显然以相同的方式构建。单独主机上的两个进程都死亡（我们在主机之间进行负载平衡）。
存储库刷新使用System.Threading.Timer完成。但是，查看我的存储库日志，没有存储库刷新的时间少于一小时，并且要刷新的最长存储库是11分钟 - 因此没有重叠。
使用ReadWriterLockSlim类保护对数据的访问。我知道这有点模糊，如果有人需要任何其他信息，我会很乐意提供我能做到的。
