Such sockets should not have users and associated files --- nothing to close.
If they do have, the service generating (apache?) them is _seriously_
broken. At least, stock apache should close them for 2 seconds, not more.



I looked at output of netstat. It evidently shows a bug in kernel.
What is version of kernel?

[ Dave! Look, he has 5000 of sockets sort of:

tcp 0 1 195.67.71.80:80 152.166.64.3:1252 LAST_ACK off (0.00/0)

Retransmission timers massively leak!
