Log Exporter stops working intermittently
Symptoms
  • Log Exporter stops sending logs after running for several hours and a restart of the Log Exporter works for another few hours.
  • In file log_indexer.elg:
    LogFormatExtractor::extractFields - Failed to read log data..
Cause

There are lots 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.
