SCTP socket lingers in CLOSE state for RHEL/CentOS

[GoogleCodeExporter]

When the SCTP socket was closed via management "m3ua asp stop XXX" and then 
started again "m3ua asp start XXX" the SCTP socket was not created and "netstat 
-pan | grep sctp" will show something like

sctp 3368 602439 X.X.X.X:2905 X.X.X.X:2905 CLOSE

Little more investigation and it turns out to be OS issue :( 
https://access.redhat.com/knowledge/solutions/56433.

There was issue with RHEL OS kernel version before kernel-2.6.32-220.el6.

The other option is set SO_LINGER in Sctp Socket 
http://docs.oracle.com/javase/7/docs/jre/api/nio/sctp/spec/com/sun/nio/sctp/Sctp
StandardSocketOptions.html#SO_LINGER

But from that link, it says its for socket configured for blocking mode only, 
while ours is non-blocking mode.

The workaround (configurable SO_LINGER option) will be covered for issue:
