Red Hat Enterprise Linux Server release 5.8 (Tikanga)
Syslog-ng version : syslog-ng-2.1.4-9.el5
Library installed : libnet-1.1.5-1.el5

/etc/syslog-ng/syslog-ng.conf file settings

options {
        sync (0);
        time_reopen (10);
        log_fifo_size (1000);
        long_hostnames (off);
        use_dns (no);
        use_fqdn (no);
        create_dirs (no);
        keep_hostname (yes);
};

source s_sys {
        file ("/proc/kmsg" log_prefix("kernel: "));
        unix-stream ("/dev/log");
        internal();
        # udp(ip(0.0.0.0) port(514));
};
source s_file { file("/opt/CA/siteminder/log/smps.log"); };
destination d_file { file("/var/log/messages"); };
destination d_remote_q1 { udp("x.x.x.x" port(514)); };
log { source(s_sys); destination(d_file); };
log { source(s_file); destination(d_file); destination(d_remote_q1); };


Syslog-ng executes fine , able to record all the OS logs . 
When i start syslog-ng the first time it polls the smps.log and forwards all the entries from that file to remote server , but after that any new events
getting logged  does not get processed even when syslog-ng is running in the background.
The issue is  syslog-ng is not able to monitor the App log  smps.log  in real time  .

This happens only for the app log , normal OS events gets processes immediately 
Tried logging a simple mesage using logger 

I did try running syslog-ng in debug mode , these are the results
 /sbin/syslog-ng -Fedv

But i do not see any debugs messages for smps.log getting processed ( even though the file is getting updated )

Any ideas
Is this is a shortcoming in syslog-ng 2.1.4 .

I cannot compile the latest version of syslog-ng since there is a limitation on my production system ( cannot compile anything due to security concerns ) 
so i am need of a syslog-ng rpm package other than 2.1.4 that works on RHEL 5    or if i can fix the issue in the existing version

Appreciate any help

Thanks
Kathi
