KB-1518 Kafka logs growing indefinitely

Symptoms

<APPIAN_HOME>/services/data/kafka-logs continues to grow and occupies a significant amount of disk space without clearing.

Cause

Service Manager tells Kafka to cleanup old logs after it has performed 3 successful checkpoints. Every time Service Manager is restarted, that count will reset. Even if checkpointing is occurring every day, if Service Manager is also restarted every day, then the logs will never get cleaned up because it won't reach the 3 successful checkpoint threshold.

Action

Manually run the checkpoint script 3 times to force Service Manager to cleanup the old logs.

Affected Versions

This article applies to Appian 17.3 and later.
