UDP socket open but not associated with a process? (v2.0.35-SMP-i386)

I've noticed an odd occurrence (problem?) on one of the servers that
I admin. There are several UDP ports that are open but don't seem to be
associated with any process...

I first discovered it by port scanning, and then looking for the
appropriate entry in lsof's output. lsof didn't mention the ports at
all, so I looked further. 'netstat -an' shows the ports, as does
/proc/udp. When I look for processes that use the inode associated
with the connection, I don't find any.

Does anyone have any ideas as to how this happened in the first
place, or what I could do to reset the connections?

The system is a dual Pentium system that seems to be quite stable
otherwise.

Here are the appropriate outputs:
netstat output for the ports:
Proto Recv-Q Send-Q Local Address Foreign Address State
udp 4528 0 0.0.0.0:998 0.0.0.0:*
udp 0 0 0.0.0.0:666 0.0.0.0:*

from /proc/net/udp:
4: 00000000:029A 00000000:0000 07 00000000:00000000 00:EAA2F606 00000000 0 0 1477214
13: 00000000:03E6 00000000:0000 07 00000000:000011B0 00:EAA2F605 00000000 0 0 236760

I can send other output if necessary.
