Fixed In Version: openshift3/logging-fluentd:v3.10.45-1
Doc Type: Bug Fix
Doc Text:
Cause: Fluentd generates events internally for some unknown reason with the OneEventStream class. This class does not have the `empty?` method. The kubernetes metadata filter was using the `empty?` method on the EventStream object to avoid processing an empty stream. Consequence: Fluentd issues many error messages complaining about a missing `empty?` method. This overwhelms the container logging and causes disk issues. Fix: The kubernetes metadata filter was changed to only call the `empty?` method on objects which have that method. Result: fluentd logs should not be filled with this message.
