If you haven't installed it, one of the best tools to put in your toolbox is lsof (list open files); it will do what you want and much, much more. Get it from here:
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.77/

The standard utility is netstat. netstat -a will display the ports in use and the processes associated with them.

if it is not installed on your system, you will need to install the utility called lsof which will help you with this.

lsof -i tcp:7546
or in a rougher way
lsof | grep 7546 (may turn out a little more than port 7546)

should show you which pid is holding the port open.

lsof can be obtained from

http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.77/

if you need it

hope this helps
