Stats and inventory updates stop. The following exception is observed:</p> <p>logoutException in thread "FlowCapableInventoryProvider" java.lang.IllegalStateException: Transaction chain has failed<br/> at com.google.common.base.Preconditions.checkState(Preconditions.java:149)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.DOMDataBrokerTransactionChainImpl.checkNotFailed(DOMDataBrokerTransactionChainImpl.java:80)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.DOMDataBrokerTransactionChainImpl.submit(DOMDataBrokerTransactionChainImpl.java:91)<br/> at org.opendaylight.controller.md.sal.dom.broker.impl.DOMForwardedWriteTransaction.submit(DOMForwardedWriteTransaction.java:142)<br/> at org.opendaylight.controller.md.sal.binding.impl.AbstractWriteTransaction.doSubmit(AbstractWriteTransaction.java:142)<br/> at org.opendaylight.controller.md.sal.binding.impl.BindingDataWriteTransactionImpl.submit(BindingDataWriteTransactionImpl.java:83)<br/> at org.opendaylight.controller.md.sal.binding.impl.BindingTranslatedTransactionChain$1.submit(BindingTranslatedTransactionChain.java:68)<br/> at org.opendaylight.controller.md.inventory.manager.FlowCapableInventoryProvider.run(FlowCapableInventoryProvider.java:124)<br/> at java.lang.Thread.run(Thread.java:745)</p> <p>The condition is very repeatable and has been reproduced on multiple systems.</p> <p>The bug is raised against md-sal, although it's not an md-sal bug.
