Okay, this is useful. Next step is to work out what that socket is
doing. Look at /proc/15044/fd. It will give you something like this:
hypochondriac:/home/dichro# ls -l /proc/157/fd
total 0
lrwx------ 1 root root 64 Aug 9 10:35 0 -> /dev/null
lrwx------ 1 root root 64 Aug 9 10:35 1 -> /dev/null
lrwx------ 1 root root 64 Aug 9 10:35 2 -> /dev/null
lrwx------ 1 root root 64 Aug 9 10:35 3 -> socket:[104]
lrwx------ 1 root root 64 Aug 9 10:35 4 -> socket:[107]
hypochondriac:/home/dichro#
Then, look socket 3 up in the tcp table.
hypochondriac:/home/dichro# egrep 104 /proc/net/tcp
11: 00000000:0016 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 104
hypochondriac:/home/dichro#
Is it wildly different to this? Can you connect to other tcp ports
on the machine? How many processes are running? Does 'dmesg' show
anything interesting?
