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 array with limited size, as result multi thread mutex is not released and the flow is stuck.
