Fluentd server throws "queue size exceeds limit" warnings in OpenShift 3.5
Issue
- Fluentd is configured for log forwarding. The following warning is noticed in the remote fluentd server log:
[warn]: emit transaction failed: error_class=Fluent::BufferQueueLimitError error="queue size exceeds limit" tag="kubernetes.var.log.containers.cbt1-2-0-2-bdc-2.log"
[warn]: suppressed same stacktrace
- Any recommendation on how to tune fluentd queue size?
Environment
