We have implemented a mechanism to limit the maximum size of the search log and click log queues to prevent excessive memory usage. When the respective queue size exceeds the configured limit, a warning is logged, and the log entry is skipped.

Details:

1. Search Log Queue

• Added a size check to addSearchLog in SearchLogHelper.java.
• If the size exceeds the configured limit (logging.search.max.queue.size), the log entry is skipped.

2. Click Log Queue

• Added a size check to addClickLog in SearchLogHelper.java.
• If the size exceeds the configured limit (logging.click.max.queue.size), the log entry is skipped.

3. Configuration Updates

• Introduced two new configuration properties in fess_config.properties:
• logging.search.max.queue.size: Sets the maximum size of the search log queue.
• logging.click.max.queue.size: Sets the maximum size of the click log queue.
• Default values for both have been set to 10000.

This change ensures more stable memory usage by avoiding unbounded growth of log queues.
