All of them. Somebody, somewhere is always scanning your outside interface trying every port.
If you want to be flooded with information, just start logging everything that gets denied by turning on ip audit.
 ip audit attack action alarm  <== send syslog message
 ip audit info action alarm
 ip audit interface outside

sho ip audit interface outside

mmm -- i already have my syslog server setup, do i need to tell the pix which syslog server to use with the above commands or will it just take the current ones?

what does sho do?
logging on
logging host

Use these commands and give the ip address in the second command to enable logging onto a syslog client. Get Kiwi Syslog (free) if you don't have one.

Cheers,

the ip audit interface outside is an invalid command.  i tried ip audit interface outbound which is the name of my interface still no good.
