program need to restart before it works

After my program (service) is installed and started on FC6, it does
not work the first time. After it is restarted, then it works.
How to fix this problem?

The spec file is like this:
....
%install
%define RPM_BUILD_DIR /usr/src/redhat/BUILD/%{name}-%{version}
rm -rf $RPM_BUILD_ROOT

mkdir -p $RPM_BUILD_ROOT/%{_prefix}/
mkdir -p $RPM_BUILD_ROOT/%{_bindirprefix}/
install $RPM_BUILD_DIR/%{name}-%{sourced_version}/myprog
$RPM_BUILD_ROOT/%{_prefix}/myprog
mkdir -p $RPM_BUILD_ROOT/etc/rc.d/init.d
install $RPM_BUILD_DIR/%{name}-%{sourced_version}/myprog.init
$RPM_BUILD_ROOT/etc/rc.d/init.d/myprog

%post
chkconfig --add myprog
chkconfig --level 0123456 myprog on

%preun
chkconfig --del myprog

Your postinstall scriptlet needs to start your program; e.g.,

service myprog on
