Should i be worrying

Hi i’m setting up my production server and after installing ruby and
rails and lighttpd and mysql. Everything seems to be working relatively
I have made small test app and it seems to work perfectly accessing the
database etc. This is my console output when running and exciting the
test app:

:~/test$ ruby script/server
=> Booting lighttpd (use ‘script/server webrick’ to force WEBrick)
=> Rails application starting on
=> Call with -d to detach
=> Ctrl-C to shutdown server (see config/lighttpd.conf for options)
Couldn’t find any pid file in ‘/home/caspar/test/tmp/pids’ matching
(also looked for processes matching

The last 2 lines is the reason for this post. What does it mean and
should I worry about it and how do I fix it if it is a problem. I
installed the setup on debian by following this tutorial:

Is it something to do with fcgi? (which i know very little about but i
believe it is installed, irb → require ‘fcgi’ ==> true)

thank you in advance for any help.
