Anyone know what could be causing this?  What uses
port 3184? From the /var/log/messages file of a web
server running FreeBSD 4.2:

Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3369
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3341
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3187
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3873
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3188
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3342
Apr 18 14:02:55 mocha /kernel: Connection attempt to UDP 127.0.0.1:3184 from 127.0.0.1:3343

Aside from the normal system processes (cron, syslog, 
etc), the server is running httpd, sshd, imapd, mysqld, 
smbd and nmbd.

netstat -an output includes many of these:

udp4       0      0  127.0.0.1.4571         *.*                    
udp4       0      0  127.0.0.1.4322         *.*                    
udp4       0      0  127.0.0.1.4168         *.*                    
udp4       0      0  127.0.0.1.4154         *.*                    

Any suggestions as to what might be the cause, or even 
how to go about investigating the cause, would be 
appreciated.

Thanks,

-Brent
