 Description   

I generated this error creating 40k LSPs between a single PCC and the artifact from
https://jenkins.opendaylight.org/integration/view/Integration%20jobs/job/integration-master-project-centralized-integration/2771/

deployed as a 3 node cluster on 10.25.2.9 , 10.25.2.10 , 10.25.2.11

  1. system:property shard.persistent ${PERSISTENCE}
    PERSISTENT="false"
  1. module-shards.conf,
    REPLICA="single"

This bug is similar to https://bugs.opendaylight.org/show_bug.cgi?id=2328 in that it is a race condition involving node creation but I’ll raise another bug as it has different stacktrace and was triggered in a different scenario.

I was not able to create the expected number of PCCs when this error occurred.

Hi Richard,

Could you please confirm if this is still an issue?

Confirmed with Richard this is no longer a problem.
