Linux 在mod-mono-server4下运行的应用程序的设置和调试

linux apache mono

Linux 在mod-mono-server4下运行的应用程序的设置和调试,linux,apache,mono,redhat,mod-mono,Linux,Apache,Mono,Redhat,Mod Mono,我有一个c#应用程序（servicebus），它运行在私有web服务器上。它的基本工作是接受一些web请求并创建其他进程来处理请求中描述的数据包。处理过程通常持续进行，可能需要数周时间 servicebus偶尔会开始消耗大量CPU。也就是说，它通常是空闲的，每天有1到2秒的CPU时间。当它进入这种奇怪的模式时，它会一直消耗100%以上的CPU。此时，如果出现新请求，apache将生成一个新的servicebus实例。此时，我将有两个servicebus副本正在运行（可能两个副本都在处理请求——我

我有一个c#应用程序（servicebus），它运行在私有web服务器上。它的基本工作是接受一些web请求并创建其他进程来处理请求中描述的数据包。处理过程通常持续进行，可能需要数周时间

servicebus偶尔会开始消耗大量CPU。也就是说，它通常是空闲的，每天有1到2秒的CPU时间。当它进入这种奇怪的模式时，它会一直消耗100%以上的CPU。此时，如果出现新请求，apache将生成一个新的servicebus实例。此时，我将有两个servicebus副本正在运行（可能两个副本都在处理请求——我不知道）

这是正常过程（通过ps-aef）：

如您所见，该应用程序是一个C#程序（使用VS 2010 for.NET 4编译），通过mono下的mod-mono-server4运行。这是一个redhat linux enterprise 6.5系统

运行了一段时间后，该进程“变得疯狂”，开始消耗大量CPU，mod mono服务器创建了一个新实例。正如你所看到的，我直到周一早上才找到它，因为它已经使用了超过2天的CPU时间。以下是新的
ps-aef
输出：

UID        PID  PPID  C STIME TTY          TIME CMD
apache    8978     1 83 Sep19 ?        2-08:26:25 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop
apache   32538     1  0 Sep21 ?        00:00:00 /opt/mono/bin/mono /opt/mono/lib/mono/4.0/mod-mono-server4.exe --filename /tmp/mod_mono_server_default --applications /:/opt/ov/vespa/servicebus --nonstop
如果您需要查看应用程序是如何配置的，我有应用程序conf.d文件中的代码段：

# The user and group need to be set before mod_mono.conf is loaded.
User apache
Group apache
# Service Bus setup
Include /etc/httpd/conf/mod_mono.conf
Listen 8081
<VirtualHost *:8081>
    DocumentRoot /opt/ov/vespa/servicebus
    MonoServerPath default /opt/mono/bin/mod-mono-server4
    MonoApplications "/:/opt/ov/vespa/servicebus"
    <Location "/">
        SetHandler mono
        Allow from all
    </Location>
</VirtualHost>
因此，我需要在命令行中输入一个
--debug
，并确定实际要杀死哪个PID。然后我可以使用中的技术来调试核心文件

注意：我已经尝试将MonoMaxCPUTime和MonoAutoRestartTime指令放入apache conf文件中来解决这个问题。问题是，当一切都是名义上的，他们工作得很好。一旦进入这种不良状态（消耗大量CPU），重启就会失败。或者更确切地说，它成功地创建了一个新流程，但未能删除旧流程（基本上是我已经处于的状态）

到目前为止的调试：我看到我的
PID=8979的日志文件在9月21日03:27停止。考虑到它通常会产生200%或300%或更多的CPU，这很容易导致“崩溃”。在查看apache日志时，我发现了一个不寻常的事件。日志的转储如下所示：
