New description:

 If the server on which NXLucene is running suffers a wild shutdown,
 NXLucene won't start again at the next machine reboot when asked
 "nxlucened start".

 This is tedious because it requires that an admin logs into the machine
 and does :
 {{{
 $ bin/nxlucened stop
 $ bin/nxlucened start
 }}}

 This is a pure integration problem and only requires shell skills to fix.

Comment (by madarche):

 Replying to [comment:3 rspivak]:
 > Is there any log message indicating the reason of failure to start?

 There isn't any log message. It's a pure integration problem and only
 requires shell skills, I should have written that (and I'm updating the
 description of the ticket accordingly).

 The problem comes from the way bin/nxlucened is written. It refuses to
 start if the PID file hasn't been removed before. And when a wild shutdown
 happens, the stop function is never called and the PID file isn't removed,
 which makes it impossible for NXLucene to restart at the next reboot.

 To reproduce:

   1. start nxlucene
   2. kill the nxlucene process
   3. try to start nxlucene, it won't
