我正在使用一个开发不佳的应用程序，由于内存泄漏或其他随机错误(如果重新启动则不会重复)，该应用程序会不断重新启动。我无权访问该代码，也无法修复它。
我开发了一个 C# 应用程序，它可以管理重新启动并在程序停止时保持程序运行，但如何识别挂起(或者当程序崩溃但 Windows 错误消息使其保持“运行”时)。
我可以使用System.Diagnostics来检测60秒内CPU时间增量是否为0(因为进程通常在25-30秒，〜50％CPU使用率)，但这可能会导致当进程空闲以获取资源时，不必要的重新启动(因为它有一个可能持续 10 分钟到 2 小时的查询密集型步骤)。
那么我如何检测程序是否正在等待 mssql 查询或网络资源，和/或如何检测和实现类似这样的内容:http://msdn.microsoft.com/en-us/library/aa373347.aspx ？
这是我使用的简化示例:
//every 60 seconds
Process[] procs;
procs = Process.GetProcessesByName(appName);
List<int> pidsRunning = new List<int>();
foreach(Process p in procs){
pidsRunning.add(p.id);
//other gathering of data and command line arguments
}
foreach(int pid in pidsLast){
if(!pidsRunning.Contains(pid)){
//do stuff if not running
}
}
pidsRunning = pidsLast;
更新
我尝试使用p.responding，但在我的例子中，即使应用程序引发了错误，它也设置为true:

最佳答案
Process[] procs;
procs = Process.GetProcessesByName(appName);
bool restartRequired = false;
foreach (Process proc in procs) {
if (!proc.Responding) {
restartRequired = true;
proc.Kill();
break;
}
}
if (restartRequired) {
Process procRun = new Process();
procRun.StartInfo.FileName = @"C:\Program Files\Winword.exe";
procRun.Start();
}
