c# - EF Core 日志记录的内存泄漏

Question

我有一个运行最新的 Ubuntu LTS 的小型 Digital Ocean Droplet(1GB 内存)。我创建了一个小的 DotNet 核心 3.1 MVC Web 应用程序(+ DotNet 核心标识)，它最终达到任务限制，然后抛出(错误的)OOM 异常。
来自 journalctl 的代表性错误消息:

 Microsoft.AspNetCore.Server.Kestrel[13] Connection id "0HM1CRI33JJJE", Request id "0HM1CRI33JJJE:0000043E": An unhandled exception was thrown by the application. System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

 at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitCache(ServiceCallSite callSite, RuntimeResolverContext context, ServiceProviderEngineScope serviceProviderEngine, RuntimeResolverLock lockType)
 at ... (etc)

重新启动时的服务状态:

Site.service - Description here
     Loaded: loaded (/etc/systemd/system/Site.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2020-07-22 17:08:51 UTC; 48s ago

      Tasks: 21 (limit: 1075)
     Memory: 103.4M

问题激活的状态输出:
