This article outlines common problems while upgrading RapidMiner Server.

Timeout during RapidMiner Server start

You might see the following log lines in the server.log file within the RapidMiner Server home directory:

ERROR [] (Controller Boot Thread) JBAS013412: Timeout after [300] seconds waiting for service container stability. Operation will roll back. Step that first updated the service container was 'add' at address '[
    ("core-service" => "management"),
    ("management-interface" => "native-interface")
ERROR [] (Controller Boot Thread) JBAS014781: Step handler$FinalRuntimeStepHandler@2821a6c1 for operation {"operation" => "add-deployer-chains","address" => []} at address [] failed handling operation rollback -- java.util.concurrent.TimeoutException

Explanation: JBoss requires a lot of time to start after the initial upgrade and then times out. This can happen because a column has been added in the new version and the existing table needs to be migrated. When such tables are large, the migration can take a lot of time and exceed the JBoss deployment time which is 300 seconds by default.

Solution: The property is used to determine how long a deployment might take before JBoss aborts the deployment. A solution to the problem is to temporarily increase the default timeout. Please use the following statement (.bat on Windows) to start RapidMiner Server for a temporary timeout increase: ./bin/ After the upgrade completed successfully the timeout increase is not required anymore.

Switching Java distributions

When switching Java distributions, e.g. from Oracle JDK to OpenJDK, temporary files of JBoss need to be cleaned. To do this, please ensure that RapidMiner Server is shut down. Afterwards, go into the installation directory of RapidMiner Server and delete the <install-directory>/standalone/tmp folder or its contents.

Overlapping Job Container ports on a single host

With RapidMiner Server 9.5 the Job Container architecture changed fundamentally and requires system ports for the Job Agent to Job Container communication which are only used locally on the machine on which the Job Agent is deployed.

In case multiple Job Agents are hosted on a single shared machine, the definition of duplicate ports might result in the following log lines:

Job container '1' cannot be spawned, because port '10000' is not available
Job container '1' started successfully with PID 'null'.

Such a scenario occurs when multiple Job Agents define the same value for the jobagent.container.listenPortRangeStart property and are hosted on a single machine. To overcome this problem, ensure to define distinct port start ranges for each deployed Job Agent on the same machine to avoid overlapping ports of Job Containers.
