Description

Hi,

This is related to AMQ-7082.

If the broker had an unclean shutdown and the recovery thread didn't find any free pages (newFreePages is empty the recovery), the broker will have a second unclean shutdown - and this will happens to any future restart as long as the number of free pages is = 0
