Bug Resolved Done Vinoth B Michael Vorburger Wed, 23 Aug 2017 10:42:29 +0000 Tue, 5 Dec 2017 14:51:12 +0000 Tue, 5 Dec 2017 14:51:12 +0000 Carbon General 0 2 <p>After analyzing the karaf log, the ELANInstance is null for the particular interfaces. The VPN interface add event for these interfaces may be failed because of OOM. It causes the NPE while retrieving the ELAN instances.</p> <p>I have added the null check before adding the ARP flow. </p> <p>Please mention the steps to reproduce to verify the fix.</p> <p>&gt; The VPN interface add event for these interfaces may be failed because of OOM</p> <p>That is very likely, because in case of an OOM we shut down Karaf completely, we don't just not do certain things... so this explanation doesn't really make that much sense.</p> <p>&gt; Please mention the steps to reproduce to verify the fix.</p> <p>I've no idea - quote <a href="https://jira.opendaylight.org/browse/CONTROLLER-1756" title="OOM due to huge Map in ShardDataTree" class="issue-link" data-issue-key="CONTROLLER-1756"><del>CONTROLLER-1756</del></a> "Our scenario is a cluster of 3 nodes with odl-netvirt-openstack being stress tested by OpenStack's rally benchmarking tool." ... so I would suggest that you propose a Gerrit doing what you think would fix this, get that reviewed and merged and we close this, and re-open it if it is still seen after merging your fix.</p> <p>Patch pushed:</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/62484/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/62484/</a></p> Development External issue ID 9035 External issue URL Rank 0|i01ug7:
