After your TCP/Server passes the fd to the Logic Server, the TCP/Server must issue a close() on the fd. This will not perform a shutdown on the socket. Later when the Logic Server dies, the exit code will also close() the socket. This will be the final process with a pointer to the socket's file table entry. So this close() will trigger a shutdown on the socket.

LEARN ABOUT PHP
memcache.pconnect
MEMCACHE.PCONNECT(3) 1 MEMCACHE.PCONNECT(3)
Memcache::pconnect - Open memcached server persistent connection
SYNOPSIS
mixed Memcache::pconnect (string $host, [int $port], [int $timeout])
DESCRIPTION
Memcache.pconnect(3) is similar to Memcache.connect(3) with the difference, that the connection it establishes is persistent. This connec-
tion is not closed after the end of script execution and by Memcache.close(3) function. Also you can use memcache_pconnect(3) function.
PARAMETERS
o $host
- Point to the host where memcached is listening for connections. This parameter may also specify other transports like
unix:///path/to/memcached.sock to use UNIX domain sockets, in this case $port must also be set to 0.
o $port
- Point to the port where memcached is listening for connections. Set this parameter to 0 when using UNIX domain sockets.
o $timeout
- Value in seconds which will be used for connecting to the daemon. Think twice before changing the default value of 1 second -
you can lose all the advantages of caching if your connection is too slow.
RETURN VALUES
Returns a Memcache object or FALSE on failure.
EXAMPLES
Example #1
Memcache.pconnect(3) example
<?php
/* procedural API */
$memcache_obj = memcache_pconnect('memcache_host', 11211);
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->pconnect('memcache_host', 11211);
?>
