我们有https://www.nuget.org/packages/Microsoft.AspNet.WebApi.SelfHost/ Web Api 服务，它运行良好。然后我们迁移到https://www.nuget.org/packages/Microsoft.AspNet.WebApi.OwinSelfHost/出现问题。我们将服务部署到服务器，40-60 分钟后我们得到错误并且服务没有响应并且我们无法停止它。然后我们终止进程并启动服务，它在接下来的 40-60 分钟内运行良好。据我了解，logentries appender 的线程或队列没有响应，因为我们在文件中看到日志，但在 logentries 中没有
<appender name="LeAppender" type="log4net.Appender.LogentriesAppender, LogentriesLog4net">
<Debug value="true" />
<HttpPut value="false" />
<Ssl value="false" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="|%level%| %m" />
</layout>
</appender>
<root>
<priority value="ALL" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="LogFileAppender" />
<appender-ref ref="LeAppender" />
</root>
错误：
XXXX-XX-XX XX-XX-XX,XXX [Logentries Log Appender] FATAL Topshelf.Runtime.Windows.WindowsServiceHost The service threw an unhandled exception System.IndexOutOfRangeException: Probable I/O race condition detected while copying memory. The I/O package is not thread safe by default.

当我启用调试模式时，我得到了更多信息。附加程序或我的应用程序有问题吗？我怎样才能获得更多信息？
