C# Mono 程序在 raspberry pi 自动执行时崩溃

Question

我们有一个 C# mono 程序运行ning on a raspberry pi 3. 当我手动执行时程序完全执行，即 sudo mono /pathtoexe 但是当它在重启时执行从 rc.local（rc.local 启动脚本文件 sudo /pathto .sh 文件，该文件又通过 sudo mono /paththexe 启动应用程序）程序仅部分执行，日志中没有可见错误。

请注意，我们试图克服的测试用例是让我们的应用程序运行在没有互联网的情况下运行，因为如果有互联网（手动和自动启动）

PI是Raspberry PI3运行ningRaspbianVersion 8 (Jessie) Mono JIT 编译器版本 3.2.8 (Debian 3.2.8+dfsg-10)

这是 rc.local 文件：

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi
#echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
#hwclock -s
#sudo /etc/init.d/watchdog start&
sudo /home/pi/Vbox/./Main.sh&
#sudo /home/pi/Vbox/./Cmu.sh&
#/usr/bin/mono-service -p:/home/pi/Vbox /home/pi/Vbox/VboxV2.exe
sudo iwconfig wlan0 txpower off
#sudo mono  /home/pi/Vbox/Vbox.exe
#sudo python /home/pi/Audio/audio_play.py
#iptables-restore < /etc/iptables.ipv4.nat
exit 0

这里要注意的主线是须藤 /home/pi/Vbox/./Main.sh&

Main.sh 文件是：

#!/bin/bash

Date=`date +%d_%m_%Y`
ErrorLogPath="/home/pi/LOG/GatewayWrapperError_$Date.log"
LogPath="/home/pi/LOG/GatewayWrapperLog_$Date.log"

## Fail over Block
function Failover
{
    ErrorIn=
    Datetime=`date +%d-%m-%Y:%H-%M-%S`
    echo "Error:  Program"
    printf "$Datetime: Error executing $ErrorIn program. Sending E-Mail notification \n">>$ErrorLogPath
    echo "Error: notification"
    #sudo mono --runtime=v4.0 /home/pi/EXE/Email.exe &
    #wait
    printf "$Datetime: Gateway notification sent \n">>$ErrorLogPath
    #sudo wvdial 3gconnect &
    #sleep 30
    echo "wvdial run succed"
    #sudo reboot
}

function main
{
        ## Executing Net_Connection_Program  Core
#        {(
 #               ExecutionDateTime=`date +%d-%m-%Y:%H-%M-%S`
  #              printf "$ExecutionDateTime: Net_Connect.sh started. \n">>$LogPath
   #             echo "Net_Connect Started"
    #            sudo /home/pi/Wrapper/./NetConnect.sh &
     #           #sudo /home/pi/Wrapper/./test.sh &
      #  )} ||
       # {(
        #        Failover "Net_Connect_Core"
         #)}


echo "Started"

    ## Executing Gateway Core
    {( 
        ExecutionDateTime=`date +%d-%m-%Y:%H-%M-%S`
        printf "$ExecutionDateTime: ES900G started. \n">>$LogPath
        echo "ES900G Started"
        sudo mono --runtime=v4.0 /home/pi/Vbox/VboxV2.exe  &> /home/pi/LOG/GatewayWrapperLog_24_09_2018.log
    )} ||
    {( 
        Failover "Gateway_Core"
         )}



}

##Master Call
main;

当程序通过脚本执行时，日志停止于此：

Function: Main Started
73574f
Vbox Version 1.0.0.0
ERROR: ConnectMQTT - Exception connecting to the broker

代码中的主要函数如下：

static void Main()
        {
            try
            {
                Thread.Sleep(5000);
                Helper.WriteLine("Function: Main Started");

                const string path = "/home/pi/Vbox/vboxid.txt";
                VboxId = File.ReadAllText(path);
                Console.WriteLine(VboxId);
                Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
                Helper.WriteLine($"Vbox Version {Version}");
                CommMqttClient = null;

                if (string.IsNullOrEmpty(VboxId)) return;

                MQTT.ConnectMqtt(); //This is last error printed in the log shown above. The program seems to crash after this

                Task.Factory.StartNew(VideoStorage.StartStorage);

                Audio = new AudioPublicAnnouncement();
                LiveStreaming = new VideoStreaming();
                VideoRetrieve = new VideoRetrieve();

                Console.ReadLine();

            }
            catch (Exception e)
            {
                Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
            }
        }

在上面的代码中，如果手动执行程序，则可以。这是我面临的主要问题..

请注意，这是以前的代码维护者编写的，我被带进来解决这个问题。他目前不可用，过去 3 天我一直在努力解决这个问题。任何帮助将不胜感激。

谢谢， Va运行

编辑：具有不停止执行的无限循环的最新代码：

                Thread.Sleep(5000);
                Helper.WriteLine("Function: Main Started");

                const string path = "/home/pi/Vbox/vboxid.txt";
                VboxId = File.ReadAllText(path);
                Console.WriteLine(VboxId);
                Version = $"{Assembly.GetExecutingAssembly().GetName().Version}";
                Helper.WriteLine($"Vbox Version {Version}");
                CommMqttClient = null;

                if (string.IsNullOrEmpty(VboxId)) return;   

                MQTT.ConnectMqtt();

                Task.Factory.StartNew(delegate
                {
                    MQTT.PublishMessage("REBOOT", $"VBOXID:{VboxId};VERSION:{Version};TIME:{DateTime.Now:dd-MM-yyyy HH-mm-ss};", false);
                });

                Task.Factory.StartNew(VideoStorage.StartStorage);

                Audio = new AudioPublicAnnouncement();
                LiveStreaming = new VideoStreaming();
                VideoRetrieve = new VideoRetrieve();

                while (true)
                {
                    Thread.Sleep(1000);
                }
            }
            catch (Exception e)
            {
                Helper.WriteLine("Error - Main: " + e.Message, ConsoleColor.Red);
            }
        }

我将此问题标记为已解决。不幸的是，它与代码的执行方式有关。详细信息在问题的最后编辑中。 @knocte 是的，我们需要尽快执行此操作，但由于它是一个跨越 500 多个站点的生产系统运行，我们需要对其采取经过计算和计划的方法。感谢您的所有投入。非常感激。干杯！
