Fixed In Version: openshift3/ose-logging-fluentd:v3.11.3-1 Doc Type: Bug Fix
Doc Text:
If this bug requires documentation, please select an appropriCause: 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.ate Doc Type value.

Correction to #c1.  Needs https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=763598 which is v1.0.3-2 of the dependency

Comment 6 Luke Meyer 2018-12-21 15:23:01 UTC 
Closing bugs that were verified and targeted for GA but for some reason were not picked up by errata. This bug fix should be present in current 3.11 release content.
