UDP_HIT but TCP_MISS on Same Request?

Is there any legitimate way that Squid 2.1.PATCH2 and 2.2.PATCH4 can
both be generating these types of log entries?:

Why is it responding UDP_HIT if it doesn't have the object, or why
isn't it using the object in cache? Here's the config file:

-----

visible_hostname proxy.omdev.com
unique_hostname proxy3.omdev.com

http_port 8080
icp_port 3130

cache_effective_user cache

Thanks for any ideas,
