Surely, but sockstat shows only the correct number of entries, I mean that
it doesn't show anything that is due to be killed. Yet netstat shows a
whole lot (about 2000!) of entries like these:

b6eccf80 stream     17      0        0        0        0        0 /var/run/daemon.sock
b647a600 stream     17      0        0        0        0        0 /var/run/daemon.sock
b6a3c080 stream     17      0        0        0        0        0 /var/run/daemon.sock
b6a3c100 stream     17      0        0        0        0        0 /var/run/daemon.sock

Only two of them seems to be usefull:
b61103c0 stream      0      0        0 b631a440        0        0 /var/run/daemon.sock
b5ec0440 stream      0      0 b5bfb2c0        0        0        0 /var/run/daemon.sock

How can I get rid of these extra ones?
