首先，如果这对您来说显然是硬件问题，而不是编程问题，我深表歉意。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），它有一大堆保存在内存中的数据存储库。有些每小时刷新一次，有些则不那么频繁。其中一些存储库在从第 3 方来源检索数据后对数据（简单 POCO）进行排序。
一旦在一个蓝月亮，我AccessViolationException在ComputeKeys一个Sort. 其中一些存储库List<T>.Sort在从第 3 方来源获取数据后使用。
执行这些类型的代码很简单，并且取决于存储库，但这里有两个示例：
pocos.Sort((a, b) => a.BookingDate.CompareTo(b.BookingDate));
或者：
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，这是我拥有的日志（时间与我拥有的另一个日志相关，显示存储库当时正在完成获取数据）：

如您所见，它几乎同时发生在两台主机上。因此，我想知道这是否不是 .NET/编程问题 - 而是硬件问题。请注意，它们都是虚拟机，并且显然以相同的方式构建。不同主机上的两个进程都死了（我们在主机之间进行负载平衡）。
存储库刷新使用System.Threading.Timer. 但是，查看我的存储库日志，没有存储库刷新少于一个小时，并且刷新的最长存储库是 11 分钟 - 所以没有重叠。
使用ReadWriterLockSlim类保护对数据的访问。我知道这有点晦涩难懂，如果有人需要任何其他信息，我很乐意提供我所能提供的。
