Question

我目前在生产服务器上面临一个该死的奇怪问题。偶尔默认的应用程序池在iis上崩溃。经过几个小时的调查，最终将问题分离出来，并创建了几行可靠地重现问题的代码：

public class DemoHttpHandler: IHttpHandler {
  public void ProcessRequest (HttpContext Context) {
    try {
      Context.Response.End();
    }
    catch(ThreadAbortException) {
    }
    finally {

    }
  }
}

此序列导致以下错误：

An unhandled exception occurred and the process was terminated.

Application ID: /LM/W3SVC/1/ROOT/scs-testint

Process ID: 4752

Exception: System.Threading.ThreadAbortException

Message: Thread was being aborted.

StackTrace:    at System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context)
   at System.Web.Hosting.PipelineRuntime.ProcessRequestNotificationHelper(IntPtr rootedObjectsPointer, IntPtr nativeRequestContext, IntPtr moduleData, Int32 flags)
   at System.Web.Hosting.PipelineRuntime.ProcessRequestNotification(IntPtr rootedObjectsPointer, IntPtr nativeRequestContext, IntPtr moduleData, Int32 flags)

导致此错误：

    Faulting application name: w3wp.exe, version: 8.5.9600.16384, time stamp: 0x5215df96
    Faulting module name: KERNELBASE.dll, version: 6.3.9600.17415, time stamp: 0x54505737

    Faulting package full name: 
    Faulting package-relative application ID:

如果我删除EMPTY ???最后阻止，一切正常，IIS不再崩溃......

public class DemoHttpHandler: IHttpHandler {
  public void ProcessRequest (HttpContext Context) {
    try {
      Context.Response.End();
    }
    catch(ThreadAbortException) {
    }
  }
}

有什么想法吗？

ThreadAbortException导致IIS崩溃应用程序池
