## Symptoms

- * Log Exporter stops sending logs after running for several hours. A restart of the Log Exporter resolves the issue for another few hours.
* In file log_indexer.elg:  
  `
  LogFormatExtractor::extractFields - Failed to read log data..`   
  **Note** : You will find *log_indexer.elg* in the following directory: *$EXPORTERDIR/targets/your_exporter_target_name/log/log_indexer.elg*

## Cause

There is a large amount of log formats (unexpected count) which overflow one of the format related arrays with limited size. As a result, multi thread mutex is not released, and the flow is stuck.
