Description of problem:
xinetd 2.3.9-0.72 leaves sockets hanging in a CLOSE_WAIT status when connections
are opened and then closed to an internal service (such as time or daytime).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.enable the "daytime" service (eg: using ntsysv)
2.telnet localhost daytime
3.The date and time will be displayed, but the socket is never closed.
4.Close the socket manually using ^] quit
5.netstat -a | grep CLOSE_WAIT


Actual Results:  The hanging socket will be displayed.

The machine eventually fails to open any further connections, and the "too many
open files" error is displayed in the log.

Expected Results:  The socket should have been closed by the xinetd server.

Additional info:

This happened to an older version of inetd but was fixed, it has now recurred in
the latest release of xinetd.

For example, see bugs # 14876, 11548, 12779, 13636, 16729, 21740, 44722, etc.

I am receiving this with the tftp service under high load (40 simultaneous
connections at the start of the day when PXE booting is starting up), and this
version -- I had to revert to the prior version to re-establish service

I see the same problem on RH 7.3: xinetd-2.3.9-0.73
Marked as duplicate of #76146 which have kernel-patch included too.
