In some cases ovsdb server or relay gets restarted, ovsdb python clients may keep the local socket open. Instead of reconnecting a lot of failures will be logged. This can be reproduced with ssl connections to the server/relay and restarting it, so it has the same IP after restart.
This patch catches the Exceptions at do_handshake to recreate the connection on the client side.
