The first WARN is similar to 942/945 about the "elan-forwarding-tables/mac-table/mac-table" and then the second WARN is the exception for 971. It is a little different in that we don't see the exception from 942/945 at this point, also 942/945 is in the log but many minutes earlier without 971. So maybe they are not really related.</p> <p><a href="https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-ocata-upstream-stateful-oxygen/369/odl_1/odl1_karaf.log.gz" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-ocata-upstream-stateful-oxygen/369/odl_1/odl1_karaf.log.gz</a></p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>2017-11-15 08:30:50,503 | WARN | rd-dispatcher-44 | ShardDataTree | 217 - org.opendaylight.controller.sal-distributed-datastore - 1.7.0.SNAPSHOT | member-1-shard-default-operational: Store Tx member-1-datastore-operational-fe-0-txn-69033-0: Conflicting modification for path /(urn:opendaylight:netvirt:elan?revision=2015-06-02)elan-forwarding-tables/mac-table/mac-table[{(urn:opendaylight:netvirt:elan?revision=2015-06-02)elan-instance-name=267f6df6-9cf8-4696-aa36-53ea595c171d}]. 2017-11-15 08:30:50,503 | WARN | ult-dispatcher-2 | ConcurrentDOMDataBroker | 217 - org.opendaylight.controller.sal-distributed-datastore - 1.7.0.SNAPSHOT | Tx: DOM-194871 Error during phase CAN_COMMIT, starting Abort OptimisticLockFailedException{message=Optimistic lock failed., errorList=[RpcError [message=Optimistic lock failed., severity=ERROR, errorType=APPLICATION, tag=resource-denied, applicationTag=null, info=null, cause=org.opendaylight.yangtools.yang.data.api.schema.tree.ConflictingModificationAppliedException: Node was deleted by other transaction.]]} at org.opendaylight.controller.cluster.datastore.ShardDataTree.lambda$processNextPendingTransaction$0(ShardDataTree.java:731)[217:org.opendaylight.controller.sal-distributed-datastore:1.7.0.SNAPSHOT] at org.opendaylight.controller.cluster.datastore.ShardDataTree.processNextPending(ShardDataTree.java:769)[217:org.opendaylight.controller.sal-distributed-datastore:1.7.0.SNAPSHOT] at org.opendaylight.controller.cluster.datastore.ShardDataTree.processNextPendingTransaction(ShardDataTree.java:716)[217:org.opendaylight.controller.sal-distributed- </pre> </div></div> <p>Still in carbon: <a href="https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-ocata-upstream-stateful-carbon/196/odl_1/odl1_karaf.log.gz" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/jenkins092/netvirt-csit-1node-openstack-ocata-upstream-stateful-carbon/196/odl_1/odl1_karaf.log.gz</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/65839/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/65839/</a> is a counter proposal to <a href="https://git.opendaylight.org/gerrit/#/c/64753/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/64753/</a> .. that should fix this <tt>OptimisticLockFailedException</tt>, because the <tt>removeEntriesForElanInterface()</tt> is changed to take <tt>WriteTransaction interfaceTx, WriteTransaction flowTx</tt> parameters which at the caller at the end of <tt>removeElanInterface()</tt> runs (now) inside a <tt>RetryingManagedNewTransactionRunner</tt>'s <tt>callWithNewWriteOnlyTransactionAndSubmit()</tt>, which will perform a few retries in case of an <tt>OptimisticLockFailedException</tt>.</p> <p>@ Michael, thanks.<br/> The patch which I have raised -&gt;
