Subject: Inconsistency in number of Unix sockets

Hello,

On kernel 2.6.29.4-167: (Fedora 11):

Why is this inconsistency in number of Unix sockets, when running the following:

 cat /proc/net/protocols | grep UNIX
UNIX       432    986      -1   ....

lsof -U | wc -l
989

netstat --unix | wc -l
906

cat /proc/net/unix | wc -l
986

On which of this statistics should we rely when we want to know how
many Unix Domain sockets do we have ? There is a variable named unix_nr_socks,
but AFAIK, the patch which used it (for /proc/net/protocols ) was
reverted lately.
