C# 创建SSL连接时的.NET Core 3.1 Alpine映像争用条件

从基于.NET Core 3.1-alpine的docker映像建立SSL连接时，我遇到了竞争情况。在使用基于Debian的图像时，我们以前从未见过这种情况发生

有人遇到过这个问题并且知道如何解决吗

它只发生在非常少量的调用中（这一次发生在MassTransit使用者中，但我们也看到它发生在控制器操作和建立MongoDB连接中）：

我个人认为这可能是.NET core Alpine映像中的一个错误，我应该在github上提交一个问题吗？

您读到错误了吗？“进程无法访问文件'/etc/ssl/certs'，因为它正被另一个进程使用。”@jdweng当然可以，但是除了CachedSystemStoreProvider之外，没有其他进程访问证书，所以这就是为什么我认为实现中存在竞争条件的原因。您是否看到了以下内容：@jdweng no。虽然我不知道是什么让您认为这是相关的，除了提到一个锁定的文件和docker？我制造了一个问题：你读到错误了吗？“进程无法访问文件'/etc/ssl/certs'，因为它正被另一个进程使用。”@jdweng当然可以，但是除了CachedSystemStoreProvider之外，没有其他进程访问证书，所以这就是为什么我认为实现中存在竞争条件的原因。您是否看到以下内容：@jdweng no。虽然我不知道是什么让您认为这是相关的，但它提到了一个锁定的文件和docker？我制造了一个问题：
