Lock/PID file contains 0, instead of actual PID

Hi,

I'm using the maint branch, so I should be up-to-date.

I'm running into an issue on a fresh install, the PID file is created, but it always contains 0.

Relevant lines in config file:

lock_file=/usr/local/nagios/var/ndo2db.pid

I tried to delete the file, it is recreated as expected on startup, but still contains 0

I'm starting ndo by hand:

/path/to/ndo2db -c /path/to/ndo2db.cfg

I tested under centos 5 and 6, 64b, same behavior.

Full test:

git clone ...
git checkout origin/maint
cd ndoutils
./configure
make all
make install
make install-config
/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg
cat /usr/local/nagios/var/ndo2db.pid           <= expecting not 0 here

Do you need me to provide more logs?
