[syslog-ng] Syslog-ng Server IP address change

[Gerardo Amaya]

Hello all. I configured a Syslog-ng server in a local LAN to make sure 
all the options were working with no problem at all. Then I moved the 
server to a different LAN.
I made all the changes needed for the linux box for the IP address 
change, but when syslog-ng start sessions it appear with the previous IP 
address, I'm sure that this session is from syslog-ng because a use a 
random port UDP 5002 and it appears the session as

192.168.4.2:5002     192.168.4.101:4342

where 192.168.4.2 is the previous IP address.

What changes do I need to make to the syslog-ng in order to use the new 
IP Address?  I hope reinstall is the last resource.

thanks in advance
