      Description

      A LogAggregation cycle might interrupt an in-progress logging. Chance of this is happening is low, however, not zero. Due to this race condition, a log entry could be entirely discarded, without being written to the log file.

      Tested with specifications:

      • Kerberos + SSL enabled
      • TFile + Rolling log aggregation

      The log file misses the 58th entry due to this behaviour.
