From af74ec9e42923ef212526d432f3415c1df41ac87 Mon Sep 17 00:00:00 2001 From: Dongmao Zhang Date: Tue, 10 Dec 2013 10:52:22 -0600 Subject: [PATCH] dlm: set zero linger time on sctp socket The recovery time for a failed node was taking a long time because the failed node could not perform the full shutdown process. Removing the linger time speeds this up. The dlm does not care what happens to messages to or from the failed node.
