Process instance stuck in timer node after javax.persistence.OptimisticLockException

Solution In Progress - Updated -

Issue

We have a pair of kie-server instances running on Openshift, using the business central operator, set with deployments 1, replicas 2, so that we can have resilience should we lose an instance.

However during a load test, we discovered that some process instances got stuck in a timer node.
