Hi

From my understanding of reading the online doc the following config should give:

• an active log named /home/johnx/MYAPP/john/logs/generic/generic.log
• a daily rollover due to the primary %d {yyyyMMdd}
  - archived log files daily or when the file size reaches 10MB in a monthly directory due to the auxilliary %d{yyyyMM,aux}
  
  Effectively I'm expecting:
  
  Active log
  /home/johnx/MYAPP/john/logs/generic/generic.log
  
  Archived logs
  /home/johnx/MYAPP/john/logs/generic/201207/
  generic.log.20120701.0 > rollover at midnight or following log event after midnight
  generic.log.20120702.0 > 10MB
  generic.log.20120702.1 > 10MB
  generic.log.20120702.3 > rollover at midnight or following log event after midnight
  etc...
  
  /home/johnx/MYAPP/john/logs/generic/201208/
  etc...
  
  Instead (see debug logs) the aux parameter is not taken into account and %d{yyyyMM,aux} is used to decide there should
  be a monthly rollover...
  
  I assume it's a bug but maybe I'm missing something...
