--------------------------------
Summary: If RuntimeException thrown during checkpoint of FlowFile
Repository, repo stops checkpointing
Key: NIFI-4322
URL: https://issues.apache.org/jira/browse/NIFI-4322
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
The WriteAheadFlowFileRepository has a 'checkpointRunnable' task that is
scheduled periodically, which is responsible for checkpointing the FlowFile
Repository. It catches IOException but no other Exceptions. So if an OOME
occurs or a RuntimeException, the repository will stop checkpointing. As a
result, it can fill all disk space and/or take a very long time to recover upon
restart, depending on how large the FlowFile repository has become.
