Description Sai Sindhur Malleni 2018-04-11 15:40:57 UTC
Description of problem:

Running performance and scale tests to create neutron resources and stress ODL Oxygen with OpenStack Queens in an HA setup we observe several open transactions using Michael Vorburger's msdsal-trace tool.
DataBroker : newWriteOnlyTransaction() 997x transactions opened here, which are not closed: (...) org.opendaylight.controller.md.sal.binding.impl.BindingDOMDataBrokerAdapter.newWriteOnlyTransaction(BindingDOMDataBrokerAdapter.java:69) (...) org.opendaylight.netvirt.neutronvpn.NeutronPortChangeListener.lambda$null$4(NeutronPortChangeListener.java:736) org.opendaylight.genius.infra.ManagedNewTransactionRunnerImpl.callWithNewWriteOnlyTransactionAndSubmit(ManagedNewTransactionRunnerImpl.java:45) org.opendaylight.netvirt.neutronvpn.NeutronPortChangeListener.lambda$handleNeutronPortUpdated$5(NeutronPortChangeListener.java:696) org.opendaylight.infrautils.jobcoordinator.internal.JobCoordinatorImpl$MainTask.runWithUncheckedExceptionLogging(JobCoordinatorImpl.java:416) org.opendaylight.infrautils.utils.concurrent.LoggingUncaughtThreadDeathContextRunnable.run(LoggingUncaughtThreadDeathContextRunnable.java:60) java.util.concurrent.ForkJoinTask$RunnableExecuteAction.exec(ForkJoinTask.java:1402) java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157)

Comment 2 Stephen Kitt 2018-04-24 13:34:43 UTC
Fixed by https://git.opendaylight.org/gerrit/71036 upstream, I’ll backport that to Oxygen and then to OSP.

Comment 7 Sai Sindhur Malleni 2018-05-25 03:03:31 UTC
Tested with puddle 2018-05-23.1 and opendaylight rpm opendaylight-8.0.0-10.el7ost.noarch
. Could not reproduce. Verified that it has been fixed.
