SCTP socket lingers in CLOSE state for RHEL/CentOS #6
Description
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.
