> 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.
