title: CGI-LUA with lighttpd: 500 internal server error
body: <p>I'm running CGI-LUA scripts with lighttpd on embedded device. The web client attempts to run via POST three scripts every 3 seconds. <br>
  Most of the time it works, but the issue is that from time to time I get 500 internal server error, like the server fails to run the script, though nothing changed and in the 'top' I see that the CPU is idle most of the time. <br> 
  I'm new to web, any ideas?</p>
