The logic in ovs-xapi-sync didn't handle the case where ovsdb-server sends
a database update before it replies to a transaction that ovs-xapi-sync
sent, like this:
ovs-xapi-sync ovsdb-server
------------- ------------
.
.
.
transaction request --->
<--- database contents update
<--- transaction reply
.
.
.
The update was not lost but ovs-xapi-sync would not process it until the
database changed again.
Bug #10082.
