Hi, The current ODE engine uses a marker file for deployed processes,so it will not happen when a node tries to deploy a process that is already known to the database, even it has changed. Then What is about this error with markAsDeployed(file) in DeploymentPoller class? Why doesn't it create a marker file successfully?
