并行任务中的System.Threading.ThreadAbortException

在我的MVC应用程序中，超级管理员可以设置一个任务队列，例如更新数据库。因此，当管理员向队列添加更新时，控制器启动一个在后台工作的新任务。但是，当您添加一些任务时，应用程序会抛出System.Threading.ThreadAbortException: Thread was being aborted。此外，堆栈跟踪表明它发生在代码的不同行上。

我还应该补充说，任务使用EF6实体与SQL-server一起工作，并且根据堆栈跟踪，它发生在对数据库执行操作之后或同时。由于更新通常很大，所以我使用db.Configuration.AutoDetectChangesEnabled = false并手动保存每20k行更改，处理并重新创建数据库。

堆栈跟踪示例:

我能做错什么吗?

public void KeepIisBackgroundThreadsAlive(Object stateInfo) {
    while (true) {

        Thread.Sleep(delay);
    }
