Port 5190 open

Hi all,

I have a VPS running CentOS 4.4 which I have just been securing. It is running apache on port 80, BIND on port 53 and ssh on an atypical port. However, when I do a portscan with nmap I find that port 5190/tcp is open. There is no daemon listening on the port (I think it is for AIM?) and in any case iptables should refuse any connection on this port. Any ideas? Should I worry about this or is the port pretty safe to leave open?

Thanks in advance

S
