commit 65cce351d74a9a637fdb2a9d5e0e63445dda9ea9 Author: Terry Wilson <[email protected]> Date: Fri Jun 4 19:47:36 2021 +0000 Use TCP keepalives for ovsdb connections When failing over OVN DB servers from one server to another, the server which originally hosted the VIP doesn't notice the connection is gone and doesn't reconnect. Ultimately, this is something that needs to be fixed in python-ovs, but setting the SO_KEEPALIVE socket option avoids the issue. This also has the benefit that the client doesn't need to send 'echo' requests, which can time out on an overloaded ovsdb-server, which causes a disconnection which then adds even more load on the ovsdb-server as it has to send the entire db contents over the wire after the connection.
