We are currently debugging the issue.</p> <p>Should this be blocker then? As bundle-based-reconciliation was never fully tested and by default it is disabled.</p> <p>(In reply to Tomas Slusny from comment #7)<br/> &gt; Should this be blocker then? As bundle-based-reconciliation was never fully<br/> &gt; tested and by default it is disabled.</p> <p>Yeah, this doesn't seem to be blocker. Only concern is controller disconnects after few attempts to resync in this case. Since submitter is testing bundle based resync, this will be blocker for their testing activity.</p> <p>Okay then, as this scenario works with default configuration, lowering the priority to critical.</p> <p>Issue is invalid as it is related to test environment and not to feature.
