Memory leaks .net core 2.0内存泄漏

我正在Ubuntu 16.04上运行.NETCore2.0应用程序。 我有一个小内存泄漏。泄漏每小时增加约1%。 我被创建了一个垃圾场，但我找不到泄漏的源头。我看到了大量的Byte[]，SQLClient和线程，但即使我在Byte[]对象上运行GCRoot（在Byte[]上的DumpHeap之后），仍然找不到源代码。 主要使用的组件有：EF芯、石英、AWS。。 当我在windows机器上运行应用程序时，内存看起来很好。 请在下面找到转储的主要部分（三小时启动时间）： 任何帮助都将不胜感激

显然，SqlClient中的MARS导致了内存泄漏。

在我的连接中，字符串MultipleActiveResultSets被设置为true。我仍然不知道为什么这只在Ububntu中受影响，而在Windows中不受影响，但当我将其设置为false时，内存将恢复稳定。

您是否可能将某些内容放入字典中，而从不删除它们？就像一个没有过期的缓存？我也有同样的问题。我怀疑石英中的问题。我使用石英3.0.0字母3。难以置信！我禁用了95%的应用程序（Log4Net、DI（Ninject）、Cache、SP atc）。现在，我的应用程序只需从AWS SQS中提取消息，并使用实体框架核心和Quartz将一些数据写入SQL server以用于计划。Quartz仅将消息推送到相同的SQS AWS。我仍然有内存泄漏！！！下一步是删除Quartz。是的，总是在没有显示任何代码的情况下责怪其他库。
