If they are network connections they should be shown as such. See example from
my Linux box:

ssh        1299 ruediger    3u  IPv4       8156                TCP euler.heimnet
z.de:32773->cerberus.heimnetz.de:ssh (ESTABLISHED)

What is the type of these descriptors (in the above example it is IPv4)?

Hm, I am not quite sure if httpd opens these files directly. These files are
often opened by some libc functions. Maybe a bug in the libc of your OS?

Please try to check if the described behaviour also happens without any 3rd
party modules loaded (Yes, I know this hurts :-)).
