Hi,

Problem that had me scratching my head for a while, with fix:

web100srv wouldn't start:

[root@ndt init.d]# ./ndt restart
Stopping web100srv: [FAILED]
Stopping fakewww: [ OK ]

Starting fakewww: [ OK ]

Nothing in logs etc etc

Digging deeper

[root@ndt init.d]# sh -x ./ndt start
...

• start_web100srv
  ++ ps auxw
  ++ grep web100srv
  ++ grep -v grep
  ++ wc -l
• cnt=1
• '[' 1 = 0 ']'
• start_fakewww
• '[' '!' 1 = 0 ']'
  ++ ps auxw
  ++ grep fakewww
  ++ grep -v grep
  ++ wc -l
• cnt=0
• '[' 0 = 0 ']'
• echo -n 'Starting fakewww:'
  Starting fakewww:+ /usr/sbin/fakewww -f /index.html -s -l /var/log/ndt/fakewww_access.log -e /var/log/ndt/fakewww_error.log

• RETVAL=0
  ...

  It doesn't even try to start web100srv

[root@ndt init.d]# ps auxw | grep web100srv
root 6930 0.0 0.0 3824 536 ? S Apr12 0:00 tail -f /var/log/ndt/web100srv.log

root 20412 0.0 0.0 4020 712 pts/1 R+ 16:15 0:00 grep web100srv

Because I was doing a tail on web100srv.log, the web100srv program itself couldn't be restarted!
Heisenberg strikes again !!

Change the greps in /etc/init.d/ndt to include the bin path

cnt=ps auxw | grep $path/web100srv | grep -v grep | wc -l

cnt=ps auxw | grep $path/fakewww | grep -v grep | wc -l

and you can now tail the log file and restart the server
