asp.net – Mono apache2 =服务暂时不可用(503)

当我尝试连接到服务器时,我收到503错误：服务暂时不可用
当我看一下errror日志时,它显示为空,我很确定这不是一个权限问题.

关于apache：

我正在使用下面的配置.

<VirtualHost *:80>
  ServerName myapp.example.com
  ServerAdmin webmaster@example.com
  DirectoryIndex index.html index.aspx
  DocumentRoot /var/www/vhosts/example.com/subdomains/myapp/httpdocs/

  # MonoServerPath can be changed to specify which version of ASP.NET is hosted
  # mod-mono-server1 = ASP.NET 1.1 / mod-mono-server2 = ASP.NET 2.0
  # For SUSE Linux Enterprise Mono Extension,uncomment the line below:
  # MonoServerPath myapp.example.com "/opt/novell/mono/bin/mod-mono-server2"
  # For Mono on openSUSE,uncomment the line below instead:
  MonoServerPath myapp.example.com "/usr/bin/mod-mono-server2"
  #mod-mono-server2

  # To obtain line numbers in stack traces you need to do two things:
  # 1) Enable Debug code generation in your page by using the Debug="true"
  #    page directive,or by setting <compilation debug="true" /> in the
  #    application's Web.config
  # 2) Uncomment the MonoDebug true directive below to enable mod_mono debugging
  MonoDebug myapp.example.com true
  # The MONO_IOMAP environment variable can be configured to provide platform abstraction
  # for file access in Linux.  Valid values for MONO_IOMAP are:
  #    case
  #    drive
  #    all
  # Uncomment the line below to alter file access behavior for the configured application
  MonoSetEnv myapp.example.com MONO_IOMAP=all
  #
  # Additional environtment variables can be set for this server instance using
  # the MonoSetEnv directive.  MonoSetEnv takes a string of 'name=value' pairs
  # separated by semicolons.  For instance,to enable platform abstraction *and*
  # use Mono's old regular expression interpreter (which is slower,but has a
  # shorter setup time),uncomment the line below instead:
  # MonoSetEnv myapp.example.com MONO_IOMAP=all;MONO_OLD_RX=1
  MonoApplications myapp.example.com "/:/var/www/vhosts/example.com/subdomains/myapp/httpdocs/"

  <Location "/">
    Order allow,deny
    Allow from all
    MonoSetServerAlias myapp.example.com
    SetHandler mono
    SetOutputFilter DEFLATE
    SetEnvIfNoCase Request_URI ".(?:gif|jpe?g|png)$" no-gzip dont-vary
  </Location>
  <IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript

谁能帮我吗.
