Let me first reframe your question as i understand.

Your webservice has created some temp files are you spawing off a thred to do some cleanup operations.

If your webservice is hosted on an IIS server then the problem could be that you IIS App pool is restarting on deletion(File Change Notification) of the directory. Try executing this code either in your app start event or before you try deleting the directory

var theRuntime = typeof(HttpRuntime).GetField("_theRuntime", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null);
var fcmField = typeof(HttpRuntime).GetField("_fcm", BindingFlags.NonPublic | BindingFlags.Instance);

var fcm = fcmField.GetValue(theRuntime);
fcmField.FieldType.GetMethod("Stop", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(fcm, null);
