Thank you for taking the time to read my message and post a response. 
I'll check the PHP forums and mailing lists.

Roughly half of the connections were from IPs that had less than 5 
connections open (most had just 1). I would think those are normal 
users. The rest of the connections were taken up by half a dozen IPs 
with this number of connections open each: 5, 5, 8, 9, 12, 24. Needing 
24 connections seems suspicious to me. But those connections were used 
to grab images that make up the design of the web site. Perhaps it is a 
user with a buggy web browser? Is there a way to tell Apache not to 
leave connections in the closing state for so long, and just to hurry 
up and close them?
